TL;DR
A protocol to isolate and expand MSCs from human umbilical cord tissue and characterize their cell surface protein expression by flow cytometry, self-renewal potential by colony-forming assay, and tri-lineage differentiation capacity is outlined.
This chapter describes two in vitro assays designed to assess the hematopoietic stem/progenitor cell (HSPC)-supporting capacity of primed MSCs, and the other is specifically aimed at their ability to support the growth of primitive HSCs.
Background Mesenchymal stem cells (MSCs) are multipotent, nonhematopoietic progenitors capable of supporting hematopoiesis and regulating immunity. Clinical studies have shown that MSCs can aid hematopoietic recovery and balance T helper 17 (Th17) and Treg cells in some aplastic anemia (AA) patients refractory to immun...
These cells can be isolated from a wide range of human tissues, including bone marrow (BM-MSCs), adipose tissue (AD-MSCs), dental tissues, such as dental pulp stem cells (DPSCs) and periodontal ligament stem cells (PDLSCs), as well as umbilical cord cells (UC-MSCs), including Wharton’s jelly–derived MSCs (UC-MSCs-WJ) a...
This integrated bone marrow organoid platform provides a physiologically relevant system for studying human hematopoietic development and immune cell differentiation and offers a scalable foundation for regenerative medicine and immunotherapy applications.
Background/Objectives: Mesenchymal stromal cells (MSCs) isolated from neonatal sources have been proposed in clinical cell therapy to enhance hematopoietic stem cell transplantation due to their hematopoietic support capacity. Here we evaluated this capacity, particularly the lymphopoietic potential that remains poorly...
Platelets originate from megakaryocytes, whose generation involves a series of biological processes including directed differentiation, proliferation, polyploidization, and maturation of hematopoietic stem cells. Abnormalities in megakaryocyte development and maturation can lead to quantitative and functional defects i...
