Regulatory T cell induced tolerance to ESC transplantation
The goals of this proposal are to utilize cell populations known to control immune reactions termed regulatory T cells and study their ability to protect embryonic stem cells (ESC) from…
Induction of immune tolerance after spinal grafting of human ES-derived neural precursors
Previous clinical studies have shown that grafting of human fetal brain tissue into the CNS of adult recipients can be associated with long-term (more then 10 years) graft survival even…
Role of HLA in neural stem cell rejection using humanized mice
One of the key issues in stem cell transplant biology is solving the problem of transplant rejection. Despite over three decades of research in human embryonic stem cells, little is…
Role of HLA in neural stem cell rejection using humanized mice
One of the key issues in stem cell transplant biology is solving the problem of transplant rejection. Despite over three decades of research in human embryonic stem cells, little is…
Engineering Embryonic Stem Cell Allografts for Operational Tolerance
Stem cells, like all transplants not derived from an identical twin, are subject to scrutiny by the immune system and, without medical interventions that suppress the immune system, are usually…
Induction of immune tolerance to human embryonic stem cell-derived allografts
Human embryonic stem cells (hESCs) can undergo unlimited reproduction and retain the capability to differentiate into all cell types in the body. Therefore, as a renewable source of various cell…
Engineering Thymic Regeneration to Induce Tolerance
A healthy immune system produces T cells that can recognize and react against foreign molecules (antigens) to protect against infection, while leaving normal host cells with “self antigens” undamaged. All…
Donor natural killer (NK) cells as “veto” cells to promote donor-specific tolerance
A major issue in the use of stem cells or in organ transplantation in general is the need to overcome graft rejection. Unfortunately, the only means currently available involves the…
Application of Tolerogenic Dendritic Cells for Hematopoietic Stem Cell Transplantation
The immune system protects us from invading pathogens, but has to be kept in check to prevent harmful responses to our own tissues. Unique immune “suppressor” cells have been recently…
Development of an immune tolerant hESC source for allogeneic cell therapy applications
Human embryonic stem cells (hESCs) are an ideal tissue source for cell replacement therapy (CRT). They have the potential for limitless self-renewal while retaining their ability to differentiate into a…
