Induced pluripotent stem cells (iPSC) shown to form multiple types of functional lymphocytes in vivo

March 29, 2016

A new study demonstrates that iPSC have the potential to differentiate into multiple lineages of functional lymphocytes, including CD4+ T cells, B cells, and natural killer cells, without bias. The ability to generate truly functional lymphocytes from somatic cell-derived hematopoietic stem cells supports the clinical application of iPSC technology to develop treatments for hematological disorders, as concluded in the study published in Stem Cells and Development, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available free on the Stem Cells and Development website until April 28, 2016.

Tianshu Lan and coauthors from Medical College of Xiamen University (Xiamen City) and Chinese Academy of Sciences (Beijing), China, provided a normal environment in which to compare the growth and differentiation capacity of hematopoietic cells derived from IPSC and from embryonic stem cells (ESC). The results show that lymphocytes generated from iPSC had the same capacity to proliferate and secrete chemical signals such as cytokines as did those from ESC when stimulated.

In the article "Induced Pluripotent Stem Cells Can Effectively Differentiate into Multiple Functional Lymphocyte Lineages In Vivo with Negligible Bias", the researchers further report that lymphocytes generated by iPSC-derived bone marrow cells could repopulate the hematopoietic systems of lethally irradiated recipient animals.

"This sort of side-by-side characterization and demonstration of the differential potential of iPSC and ESC is an absolute necessity to elevate what we do in stem cell research from conjecture and assumption to rigorous applicability and then clinical translation," says Editor-in-Chief Graham C. Parker, PhD, The Carman and Ann Adams Department of Pediatrics, Wayne State University School of Medicine, Detroit, MI.

The Lymphocytes: Role in Health & Diseases
by Gaurav Agrawal (Author)


Life is a never-ending battle against infectious micro-organisms. Most of the time, this struggle rages below the radar screen of our awareness as our body’s many innate defense mechanisms prevail keeping us in a state of relative health. However,occasionally these defenses are breached, typically by pathogens that have evolved specialized strategies to subvert or avoid rejection by hard-wired innate immune mechanisms. Such infections require more sophisticated and flexible defense strategies afforded by lymphocytes that make up our adaptive immune system.Adaptive immune responses are characterized by the capacity to recognize and remember pathogen-specific antigens.Although these general principles are now well-established, many of the all important fine details are still...
