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

The new stem cell biology: something for everyone

TL;DR: This review sets out to provide a critical evaluation of the current literature in the adult stem cell field, and investigates the ability of multipotential adult stem cells to cross lineage boundaries (transdifferentiate).

Stem cell in gastrointestinal structure and neoplastic development
Mairi Brittan,Nicholas A. Wright +1 more
TL;DR: With the emergence of the molecular pathways governing gastrointestinal stem cell function, and the identification of putative intestinal molecular stem cell markers, such as Musashi-1, comes a clearer insight into the properties of the gastrointestinal stem cells.

C1qRp defines a new human stem cell population with hematopoietic and hepatic potential

TL;DR: The identification of human hepatocytes in mouse livers indicates that the NOD/SCID (nonobese diabetic/severe combined immunodeficient) mouse model can be a valuable tool to study the differentiation potential of adult human stem cells.

TL;DR: Light microscopy demonstrated that transplanted cells had differentiated into cells with myocyte-like characteristics and a robust increase of neovascularization as evidenced by von Willebrand factor-positive angioblasts and capillaries in transplanted hearts.

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.

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.
