... reduced the number of B1a cells, MZBs, ILC2s and Tregs, both in situ and upon transplantation, indicating an intrinsic and essential role for IL7Rα. Surprisingly, reciprocal transplants of wild-type HSCs showed that an IL7Rα −/− environment selectively impaired reconstitution of TLCs when compared...

Crucially, these human LGE progenitors readily differentiate into postmitotic neurons expressing the striatal projection neuron signature marker DARPP32, both in culture and following transplantation in the adult...

.... 2009 Glia Myelination Neuron-glial switch Purmorphamine Transplantation Oligodendrocytes, the myelinating glia in the central nervous system (CNS),are differentiated chiefly from neuroepithelial (NE) cells in the ventral neural tube. These NE cells express the helix-loop-helix...

These results demonstrate that activation of the PI3K-Akt pathway plays a central role in the self-renewal division of spermatogonial stem cells. 13 3...

Here, we demonstrate that the testicular somatic environment of XX/Sry males is defective in supporting the later phases of spermatogenesis. Spermatogonial transplantation analyses using XX...

AHNPs longitudinally maintain the ability to generate both glial and neuronal cell types in vivo and in vitro,and are amenable to genetic modification and transplantation. These findings suggest an unprecedented degree...

Primordial germ cell transplantation techniques will also provide a novel tool to assess the developmental potential of PGCs, such as those manipulated in vitro or recovered...
