A necessidade atual em se continuar a pesquisar com células-tronco embrionárias
Embryonic stem cells are pluripotent and able to generate all cell types of the body, being the most promising cells to the study for regenerative medicine. Following the differentiation path, there are adult stem cells, ...
Epiblast embryo stem cells give origin to adult pluripotent cell populations: Primordial germ cell, pericytic and haematopoyetic stem cells. A review Las células madre del epiblasto dan origen a poblaciones de células pluripotentes adultas: Células germin
(Universidad de la Frontera, 2009)
Adult stem cells are great promise to the future of regenerative therapy, and understanding of its embryonic origin permit the discrimination of stem cell sources. Embryonic stem cells derived from inner cell mass of ...
Hedgehog-GLI signaling regulates the behavior of cells with stem cell properties in the developing neocortex
Stem cells are crucial for normal development and homeostasis, and their misbehavior may be related to the origin of cancer. Progress in these areas has been difficult because the mechanisms regulating stem cell lineages ...
Stem cell Researches in Brazil: Present and Future Challenges
(SPRINGER HEIDELBERG, 2009)
A bill allowing researches with human embryonic stem cells has been approved by the Brazilian Congress, originally in 2005 and definitively by the Supreme Court in 2008. However, several years before, investigations in ...
Isolation, Characterization, and Differentiation Potential of Canine Adipose-Derived Stem Cells
(COGNIZANT COMMUNICATION CORP, 2010)
Adipose tissue may represent a potential source of adult stem cells for tissue engineering applications in veterinary medicine. It can be obtained in large quantities, under local anesthesia, and with minimal discomfort. ...
Dual origin of mesenchymal stem cells contributing to organ growth and repair
(NATL ACAD SCIENCES, 2011)
In many adult tissues, mesenchymal stem cells (MSCs) are closely associated with perivascular niches and coexpress many markers in common with pericytes. The ability of pericytes to act as MSCs, however, remains controversial. ...
