In Vitro Differentiation of Human Umbilical Cord Blood CD133(+)Cells into Insulin Producing Cells in Co-Culture with Rat Pancreatic Mesenchymal Stem Cells.

Objective: Pancreatic stroma plays an important role in the induction of pancreatic cells by the use of close range signaling. In this respect, we presume that pancreatic mesenchymal cells (PMCs) as a fundamental factor of the stromal niche may have an effective role in differentiation of umbilical cord blood cluster of differentiation 133(+) (UCB-CD133(+)) cells into newly-formed β-cells in vitro.

Materials And Methods: This study is an experimental research.

Short-term ferrous sulfate supplementation in female blood donors.

Background: Iron deficiency is a public problem in women, which contributes to the high percentage of deferred blood donations in this group. This study evaluated the effect of iron supplementation in improving iron stores to promote safe blood donation in women.

Study Design And Methods: A total of 412 female blood donors were randomly recruited for the study.

In vitro Evaluation of Cytarabin Induced Apoptosis in Leukemic Blasts.

Apoptosis, or active cell death, is a specific mode of cell death, which is characterized by morphological changes such as chromatin condensation, fragmentation of the nucleus, cytoplasmic retraction and appearance of apoptotic bodies' containing apparently intact organelles. Apoptosis occurs in physiological conditions as a regulatory mechanism of tissue growth, where cell proliferation is balanced. The aim of this research was to study the ability of Fas to initiate apoptosis in vitro before and after treatment with Cytarabin on tissue culture and to correlate the response.

Expression of Fas Antigen (CD95) on Human Leukemic Cells and Assessment of Apoptosis on Fas+ and Fas-Samples by Flowcytometry Method.

Regulation of normal cell growth and turnover is balanced between cell proliferation, cell differentiation and apoptosis.A disruption of this balance is thought to be an important event leading to carcinogenesis .One of the effector molecules in apoptosis is Fas antigen .
