Derivation of male germ cell-like lineage from human fetal bone marrow stem cells.

Mesenchymal stem cells derived from bone marrow are a well characterized population of adult stem cells that can be maintained and propagated in culture for a long time with the capacity to form a variety of cell types. Reports have shown that murine and human embryonic stem cells can differentiate into primordial germ cells and then to early gametes. Evidence has indicated that some adult stem cells also have the potential to differentiate into germ cells.

Structural and functional differences between KRIT1A and KRIT1B isoforms: a framework for understanding CCM pathogenesis.

KRIT1 is a disease gene responsible for Cerebral Cavernous Malformations (CCM). It encodes for a protein containing distinct protein-protein interaction domains, including three NPXY/F motifs and a FERM domain. Previously, we isolated KRIT1B, an isoform characterized by the alternative splicing of the 15th coding exon and suspected to cause CCM when abnormally expressed.

Contribution of stem cells to kidney repair.

The potential role of stem cells in the repair of glomerular and tubular injury is under intensive investigation. Several studies have addressed the role of endogenous bone-marrow (BM)-derived stem cells (SC) in the repair of renal injury. Some reports indicate that BM-derived SC are capable of engraftment into damaged nephrons, although the lineage of SC recruited has not been established.
