A necessidade atual em se continuar a pesquisar com células-tronco embrionárias
(2013-05-01)
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, ...
Mast cells modulate the inflammatory process in endotoxin-induced uveitis
(2011-05-30)
Purpose: To investigate the role of mast cells and annexin-A1 (Anxa1) in endotoxin-induced uveitis (EIU). Methods: EIU was induced by injection of lipopolysaccharide (LPS) into the paws of rats, which were then sacrificed ...
Effects of acetylsalicylic acid and acetic acid solutions in VX2 carcinoma cells. In vitro analysis
(2006-05-01)
Purpose: To analyze, in vitro, the effects of acetylsalicylic acid (aspirin) and acetic acid solutions on VX2 carcinoma cells in suspension and to examine the correlation between these effects and neoplastic cell death. ...
Infection and apparent invasion of Vero cells by Paracoccidioides brasiliensis
(1994-01-01)
Paracoccidioides brasiliensis probably uses many different mechanisms to establish itself in the host and cause disease. In this work, we assess an in vitro model system which uses cultured mammalian cells to investigate ...
The thrombocyte aggregation process in the turtle Phrynopys hilarii (Chelonia). An ultrastructural study
(2002-07-01)
This study investigates the thrombocyte aggregation process in the South American fresh water turtle (Phrynopys hilarii) using electron microscopy. Blood was taken from surgically exposed lateral neck vessels often turtles ...
Autologous stem cell transplantation for early type 1 diabetes mellitus
(TAYLOR & FRANCIS LTD, 2008)
Type 1 diabetes mellitus (T1DM) is the result of the autoimmune response against pancreatic insulin producing cells. This autoimmune response begins months or even years before the first presentation of signs and symptoms ...
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 ...
