Isolation and Expansion of Oligodendrocytes from Thawed, Cryopreserved Human Umblilical Cord Blood

The Effects of EGTA on the Quality of Fresh and Cryopreserved-Thawed Human Spermatozoa

Background: Sperm cryopreservation-thawing process has damaging effects on the structure and function of sperm, namely cryoinjury. Calcium overload has been reported as a postulated mechanism for sperm damage during the first steps after thawing. This study was designed to assess the intracellular calcium (Ca2+i) after cryopreservation and to clarify the role of a calcium chelator ethylene glyc...

Expansion of Human Tregs from Cryopreserved Umbilical Cord Blood for GMP-Compliant Autologous Adoptive Cell Transfer Therapy

Umbilical cord blood is a traditional and convenient source of cells for hematopoietic stem cell transplantation. Thymic regulatory T cells (Tregs) are also present in cord blood, and there is growing interest in the use of autologous Tregs to provide a low-risk, fully human leukocyte antigen (HLA)-matched cell product for treating autoimmune diseases, such as type 1 diabetes. Here, we describe...

Isolation of Endothelial Progenitor Cells from Cord Blood and Induction of Differentiation by Ex Vivo Expansion

Endothelial progenitor cells (EPCs) have been reported to possess the capacity to colonize vascular grafts and hold promise for therapeutic neovascularization. However, limited quantities of EPCs have been the major factor impeding effective research on vasculoangiogenesis. In this study, cytokine and culture conditions necessary for the provision of large quantities of endothelial cells (ECs) ...

Secreted Factors from Human Umbilical Cord Blood Cells Protect Oligodendrocytes from Ischemic Insult

EXPANSION OF HUMAN CORD BLOOD PRIMITIVE PROGENITORS IN SERUM-FREE MEDIA USING HUMAN BONE MARROW MESENCHYMAL STEM CELLS

Ex vivo expansion of human umbilical cord blood cells (HUCBC) is explored by several investigators to enhance the repopulating potential of HUCBC. The proliferation and expansion of human hematopoietic stem cells (HSC) in ex vivo culture was examined with the goal of generating a suitable clinical protocol for expanding HSC for patient transplantation. Using primary human mesenchymal stem ...
