City of Hope’s Train, Educate and Accelerate Mastery of Stem cell research (TEAMS) program was built around four key areas of regenerative medicine research: Cancer Stem Cells, Hematopoietic Stem Cells, Tissue-Specific Stem Cells and Human Pluripotent Stem Cells. We recruited well-qualified mentors to support the training of our 14 CIRM TEAMS trainees. Each of the trainees was assigned a project that allowed them to develop the conceptual, technical and ethical skills to explore the topic. Within the field of Cancer Stem Cells we had four trainees. One trainee focused on developing in vitro growth conditions to optimize expansion of luminal epithelial cells and c-KIT+ progenitor cells to explore the early stages of breast cancer. A second trainee focused on developing a fluorescent marker to allow for the characterization of a CAR-T cell population as it interacts with the targeted brain tumor. Two students focused on establishing transgenic mouse models to explore the impact of androgen receptor, hepatocyte growth factor and human c-MET on the development of prostate cancer tumors. Within the field of Hematopoietic Stem Cells one trainee explored the impact of SGF29, a protein that recognizes methylated histones and modulates transcription, in leukemic cancer stem cells. To approach this question a CRISPR-Cas9 approach was used to delete the SGF29 gene and assess its impact on cellular growth. Four trainees worked within the field of Tissue-Specific Stem Cells. One student explored the impact of modulating the cohesion complex on the growth and behavior of insulin-producing -cell. Knocking out one of the cohesin complex components, SMC3, allowed the trainee to explore the impact of cohesin during early neonatal development and later as the mouse develops into an adult. The trainee discovered that cohesin is a critical component of the replication process, which is the primary mechanism of -cell mass expansion. A second trainee examined the relationship between aging and the activation of adipocyte progenitor cells. This analysis led to the discovery of a population of preadipocyte cells whose gene expression is remodeled in an age-specific fashion. A third trainee looked at the relationship between -cell and endothelial cell dysfunction and the role of endothelial Argonaute 1(AGO1) in this process. Specifically, the trainee looked at the ability of an endothelial cell AGO 1 gene knockout to rescue streptozotocin-induced damage in female mice. This was assayed by looking at insulin sensitivity, glucose regulation, and body weight. Our fourth trainee participated in a project directed at modifying oleanolic acid to improve its water solubility and improve its absorptive characteristics. The trainee focused on taking analogs of oleanolic acid and analyzing their Octanol-Water Partition Coefficient using High-Performance Liquid Chromatography. The ultimate goal of this research is to develop analogs of oleanolic acid to take advantage of its robust anti-inflammatory properties for clinical applications. With the field of Human Pluripotent Stem Cells we supported four trainees. Our first trainee focused on the impact of pseudouridine in coding and noncoding RNAs as an effector of glioblastoma stem cells (GSC) and the development of glioblastoma multiforme brain tumors. Using CRISPR-Cas9 the trainee mutated specific pseudoruridylation sites in noncoding RNAs of interest in GSCs. These modifications led a reduction of cellular growth as compared to a control population of untreated cells. A second trainee examined the role of Sae2 in DNA replication, a critical step in growth and self-renewal of pluripotent stem cells. Understanding the activity of this gene will allow for an improved understanding of how cells can survive DNA damage leading to genomic rearrangements that support the initial stages of tumorgenesis and subsequent cancer development. Our third trainee in this group focused on the generation of human artificial thymic organoids (ATO) from umbilical cord blood derived hematopoietic stem cells to allow for the study of T cell development. Using ATOs developed from different cell lines the trainee assessed the ability to support CD34+ differentiation. The ultimate goal is to use ATOs to develop cancer fighting T cells for immunotherapy applications. Our final student worked to introduce a “suicide gene” construct into engineered in iPSCs for the generation of the insulin-producing -cell to treat type 1 diabetes patients. The suicide gene would allow for the removal of undifferentiated iPSCs that could potentially become tumors following transplantation. This summer our CIRM TEAMS cohort has successfully delved into a wide range of topics impacting regenerative medicine and stem cell biology. We are confident that this experience has created a platform for them to launch into careers that will impact these fields of research in the future.

Grant Application Details

Application Title:

Train, Educate, and Accelerate Mastery of Stem cell research (TEAMS) program

Public Abstract:

It is well documented that trainees from groups underrepresented in the STEM fields leave the research workforce pipeline, with many progressively losing interest in research-intensive careers. To overcome this, we will leverage our institution’s long-standing success in education and training toward engaging underrepresented individuals in the field of regenerative medicine. The Train, Educate, and Accelerate Mastery of Stem cell research (TEAMS) program’s primary goal is to develop and maintain a robust pipeline of students excited about regenerative medicine research to become the next generation of researchers. We will inspire, educate, and motivate qualified candidates from southern California’s diverse populations, enabling them to master critical regenerative medicine knowledge and skills using a multidisciplinary approach. Under the umbrella of a long-standing, renowned summer academy, the 10-week TEAMS program will select 10 high school students (over the age of 16) to participate in a 10-week program that places trainees in 10 (of 23 potential) laboratories focused on regenerative medicine research. Our goal is for TEAMS to become a focal point for mentoring and training a diverse pipeline of regenerative medicine researchers to address disparities in its application. Strong mentorship, especially through formalized programs, can enable trainees to navigate a research career pathway and strengthen their commitment to a regenerative medicine career as early as possible.

Our institution is home to a diverse group of researchers who are exploring a broad array of regenerative medicine topics, and actively promotes diversity, equity, and inclusion in our workforce. Our mentors have historically embraced the opportunity to host CIRM-SPARK trainees, ensuring a superlative first-hand experience in pursuing a hypothesis-driven, regenerative medicine-focused research project. Early exposure to biomedical research allows trainees to fully appreciate all aspects of the scientific process, including developing a hypothesis, designing experiments, performing experiments, gathering and analyzing data, and drawing conclusions. By coupling this with clinical interactions, training in cutting-edge core facilities, participation in an established personal and professional development program, and community outreach opportunities, we will ensure that each TEAMS trainee is inspired by the untapped potential of biomedical research. Together, these experiences will provide a broad educational foundation as well as stimulate an interest in pursuing regenerative medicine-based research in the future.

We have a robust history of supporting training of this kind, exemplified by our summer academy, a recently concluded CIRM-SPARK program, and other federally funded programs to engage students in the research pipeline. Many alumni of these programs (61.5%) currently remain in a science-based career pipeline including biomedical research and medicine.

Statement of Benefit to California:

California leads the world in regenerative medicine discovery. Despite this significant accomplishment, our regenerative medicine treatments have been minimally evaluated in people of color. Most clinical trial participants are non-Hispanic European-Americans. Among researchers, disparities in training occur throughout the entire regenerative medicine research pipeline. Latinx/Hispanic- or African-Americans account for only a small number of research scientists and <2% of physicians conducting clinical trials. The population of southern California represents a melting pot that is culturally and racially diverse. A 2019 population estimate reported Los Angeles County to have a population of 10,039,107, which included 26% white, 48.6% Hispanic, 15% Asian, 9% African American, and 2% American Indian/Alaska Native/Pacific Islander, with similar demographics in neighboring counties. Located in southern California, our proposed Train, Educate, and Accelerate Mastery of Stem cell research (TEAMS) program recognizes our opportunity to enhance the scientific workforce by reducing the barriers to success for groups of people who face unique challenges in entering the regenerative medicine field. The benefits of diversifying the workforce include promoting innovation and global competitiveness and increasing the likelihood that biomedical advances will benefit our diverse population, including medically underserved groups. To promote the development of a diverse workforce that reflects our state and local communities, we will offer local high school students the chance to engage in science as a hands-on experience rather than as a lecture and textbook exercise. The TEAMS program will leverage our majority-minority community and our institution’s diversity training programs and world-renowned regenerative medicine discovery resources. Trainees will gain a general understanding of a range of biomedical topics and expand their personal and professional development under the guidance of our dedicated faculty and staff. Carrying out experiments in a model system is not limited to simply applying a protocol to arrive at a particular endpoint, it is also necessary to understand both the ethical implications of the work and the potential impact it may have on patients. Thus, TEAMS trainees will also explore bioethical issues surrounding regenerative medicine, including representation and disparities. Our institution is nationally recognized for our clinical application of regenerative medicine in cancer and diabetes, and trainees will also interact with our clinicians and patient advocates working in the areas of bone marrow transplant, islet cell transplantation, and CAR T cell therapy. This opportunity will provide trainees with a unique perspective of the very real impact that regenerative medicine-based therapies have on the lives of patients. Our goal is to build a diverse regenerative medicine pipeline and address disparities in our community.
