BACKGROUND This study was conducted to evaluate the expression of the activated leukocyte cell adhesion molecule (ALCAM) in pancreatic cancer (PAC) and to determine whether or not the ectodomain shedding of ALCAM (s-ALCAM) could serve as a biomarker in the peripheral blood of PAC patients. MATERIAL AND METHODS Tissue specimens and blood sera of patients with PAC (n = 264 and n = 116, respecti...
The T lineage glycoprotein CD6 is generally considered to be a costimulator of T-cell activation. Here, we demonstrate that CD6 significantly reduces early and late T-cell responses upon superantigen stimulation or TCR triggering by Abs. Measuring calcium mobilization in single cells responding to superantigen, we found that human T cells expressing rat CD6 react significantly less well compare...
BACKGROUND AND OBJECTIVES We previously found that human fetal lung is a rich source of mesenchymal stem cells (MSC). Here we characterize and analyze the frequency and function of MSC in other second-trimester fetal tissues. DESIGN AND METHODS Single cell suspensions of fetal bone marrow (BM), liver, lung, and spleen were made and analyzed by flow cytometry for the expression of CD90, CD105,...
Differentiation of adipocytes and osteocytes from human adipose and placental mesenchymal stem cells
Objective(s):Mesenchymal stem cells (MSC) can be isolated from adult tissues such as adipose tissue and other sources. Among these sources, adipose tissue (because of easy access) and placenta (due to its immunomodulatory properties, in addition to other useful properties), have attracted more attention in terms of research. The isolation and comparison of MSC from these two sources provides a ...
Metastatic colorectal cancer remains a serious health concern with poor patient survival. Although 5-Fluorouracil (5-FU) or 5-FU plus oxaliplatin (FOLFOX) is the standard therapy for colorectal cancer, it has met with limited success. Recurrence of the tumor after chemotherapy could partly be explained by the enrichment of the chemo-resistant sub-population of cancer stem cells (CSCs) that poss...
Abstract Several hypotheses have been proposed, relating to the potential genesis of follicular cells in ovarian niche. Reports using mice as an experimental model suggested that ovaries may contain stem are likely involved formation new follicles adult reproductive life. Over recent years, various types identified and described confirm or disprove existence cells. Most research is focused on g...
