TLDR
It is demonstrated that mouse bone marrow cells can fuse spontaneously with embryonic stem cells in culture in vitro that contains interleukin-3, which, without detailed genetic analysis, might be interpreted as ‘dedifferentiation’ or transdifferentiation.Abstract:
Recent studies have demonstrated that transplanted bone marrow cells can turn into unexpected lineages including myocytes, hepatocytes, neurons and many others. A potential problem, however, is that reports discussing such 'transdifferentiation' in vivo tend to conclude donor origin of transdifferentiated cells on the basis of the existence of donor-specific genes such as Y-chromosome markers. Here we demonstrate that mouse bone marrow cells can fuse spontaneously with embryonic stem cells in culture in vitro that contains interleukin-3. Moreover, spontaneously fused bone marrow cells can subsequently adopt the phenotype of the recipient cells, which, without detailed genetic analysis, might be interpreted as 'dedifferentiation' or transdifferentiation.read more

Transplanted mesenchymal stem cells accelerate glomerular healing in experimental glomerulonephritis.
TL;DR: Even low numbers of MSC can markedly accelerate glomerular recovery from mesangiolytic damage possibly related to paracrine growth factor release and not to differentiation into resident glomersular cell types or monocytes/macrophages.
Journal ArticleDOI
In vivo contribution of murine mesenchymal stem cells into multiple cell-types under minimal damage conditions.
TL;DR: The data indicate that even in the absence of substantial injury, phenotypically defined murine mesenchymal stem cells could acquire tissue specific morphology and antigen expression and thus contribute to different tissue cell-types in vivo.

Adult bone marrow-derived cells trans-differentiating into insulin-producing cells for the treatment of type I diabetes

TL;DR: It is demonstrated that adult BM cells are capable of trans-differentiating into a pancreatic lineage in vitro and may represent a pool of cells for the treatment of diabetes mellitus.

Human embryonic stem cells: research, ethics and policy
TL;DR: Some of the ethical issues surrounding the use of human embryos and human ES cells in the context of state-of-the-art research on the development of stem cell based transplantation therapy are addressed.

Apoptosis and genomic instability.
Boris Zhivotovsky,Guido Kroemer +1 more
TL;DR: Genomic instability is intrinsically linked to significant alterations in apoptosis control and DNA-repair proteins can regulate apoptosis, with important implications for the pathophysiology of cancer.

TL;DR: Adult stem cells isolated from marrow aspirates of volunteer donors could be induced to differentiate exclusively into the adipocytic, chondrocytic, or osteocytic lineages.

Viable offspring derived from fetal and adult mammalian cells
TL;DR: The birth of lambs from differentiated fetal and adult cells confirms that differentiation of that cell did not involve the irreversible modification of genetic material required for development to term and reinforces previous speculation that by inducing donor cells to become quiescent it will be possible to obtain normal development from a wide variety of differentiated cells.

Formation of Pluripotent Stem Cells in the Mammalian Embryo Depends on the POU Transcription Factor Oct4

TL;DR: It is reported that the activity of Oct4 is essential for the identity of the pluripotential founder cell population in the mammalian embryo and also determines paracrine growth factor signaling from stem cells to the trophectoderm.

TL;DR: Transplantation of genetically marked bone marrow into immunodeficient mice revealed that marrow-derived cells migrate into areas of induced muscle degeneration, undergo myogenic differentiation, and participate in the regeneration of the damaged fibers.

TL;DR: It is shown that rare cells that home to bone marrow can LTR primary and secondary recipients, and this finding may contribute to clinical treatment of genetic disease or tissue repair.
