The Global ETD Search service is a free service for researchers
to find electronic theses and dissertations. This service is
provided by the
Networked Digital Library of Theses and Dissertations.
Our metadata is collected from universities around the world. If you manage a university/consortium/country archive and want to be added, details can be found on the NDLTD website.

"Células mononucleares de sangue de cordão umbilical e de sangue periférico estimulado com fator de crescimento granulocítico (G-CSF) : análise da proliferação e de apoptose in vitro" / Mononuclear cells from umbilical cord blood and from granulocyte colony-stimulating factor (G-CSF) mobilized peripheral blood. Analysis of proliferation and apoptosis in vitroRibeiro, Andreza Alice Feitosa 08 September 2003 (has links)
Células mononucleares de sangue de cordão umbilical (SCU) e sangue periférico mobilizado (SPM) com G-CSF, foram cultivadas in vitro com citocinas, na presença ou não de estroma de medula óssea. Os objetivos foram avaliar a capacidade proliferativa de células progenitoras, a ocorrência de apoptose e expressão de integrina. Nas culturas sem estroma, a celularidade aumentou 5 vezes (SCU) e não se alterou nas de SPM. O total de células CD34+ caiu em ambas culturas. Com estroma, o total de células nucleadas aumentou 7 vezes (SCU) e 2,3 vezes (SPM). O total de células CD34+ permaneceu o mesmo. A apoptose foi menor nas culturas de SCU. A expressão de integrina caiu, na população de células CD34+ e de CD45+ / Mononuclear cells from umbilical cord blood (UCB) and G-CSF mobilized peripheral blood (MPB), were cultured in vitro, in the presence of cytokines, with or without bone marrow stroma. The aims were to evaluate the proliferative response of progenitor cells, occurrence of apoptosis and expression of adhesion molecule. In cultures without stroma, cellularity increased 5-fold for UCB, but has not changed for MPB. The number of CD34+ cells has dropped in both culture. With stroma, total nucleated cells had a 7-fold increse (UCB) and a 2,3-fold (MBP), however, CD34+ cells number has not changed. Apoptosis was lower in UCB culture. The expression of integrin decreased, in the CD34+ and CD45+ population
