Serum-free methylcellulose-based medium with recombinant cytokines for human cells
概述
MethoCult™ SF H4436 is a complete serum-free methylcellulose-based medium for the growth and enumeration of hematopoietic progenitor cells in colony-forming unit (CFU) assays of human bone marrow, mobilized peripheral blood, peripheral blood, and cord blood samples. MethoCult™ SF H4436 is formulated to support optimal growth of erythroid progenitor cells (BFU-E and CFU-E), granulocyte-macrophage progenitor cells (CFU-GM, CFU-G and CFU-M), and multipotential granulocyte, erythroid, macrophage, megakaryocyte progenitors (CFU-GEMM) under defined serum-free conditions.

Tenascin C promotes hematoendothelial development and T lymphoid commitment from human pluripotent stem cells in chemically defined conditions Stem Cell Reports 2014 DEC
Abstract
The recent identification of hemogenic endothelium (HE) in human pluripotent stem cell (hPSC) cultures presents opportunities to investigate signaling pathways that are essential for blood development from endothelium and provides an exploratory platform for de novo generation of hematopoietic stem cells (HSCs). However, the use of poorly defined human or animal components limits the utility of the current differentiation systems for studying specific growth factors required for HE induction and manufacturing clinical-grade therapeutic blood cells. Here, we identified chemically defined conditions required to produce HE from hPSCs growing in Essential 8 (E8) medium and showed that Tenascin C (TenC), an extracellular matrix protein associated with HSC niches, strongly promotes HE and definitive hematopoiesis in this system. hPSCs differentiated in chemically defined conditions undergo stages of development similar to those previously described in hPSCs cocultured on OP9 feeders, including the formation of VE-Cadherin(+)CD73(-)CD235a/CD43(-) HE and hematopoietic progenitors with myeloid and T lymphoid potential.
3D microcarrier system for efficient differentiation of human pluripotent stem cells into hematopoietic cells without feeders and serum [corrected]. Regenerative medicine 2013 JUL
Abstract
BACKGROUND Human embryonic stem cells (hESCs) have been derived and maintained on mouse embryonic fibroblast feeders to keep their undifferentiated status. To realize their clinical potential, a feeder-free and scalable system for large scale production of hESCs and their differentiated derivatives is required. MATERIALS & METHODS hESCs were cultured and passaged on serum/feeder-free 3D microcarriers for five passages. For embryoid body (EB) formation and hemangioblast differentiation, the medium for 3D microcarriers was directly switched to EB medium. RESULTS hESCs on 3D microcarriers maintained pluripotency and formed EBs, which were ten-times more efficient than hESCs cultured under 2D feeder-free conditions (0.11 ± 0.03 EB cells/hESC input 2D vs 1.19 ± 0.32 EB cells/hESC input 3D). After replating, EB cells from 3D culture readily developed into hemangioblasts with the potential to differentiate into hematopoietic and endothelial cells. Furthermore, this 3D system can also be adapted to human induced pluripotent stem cells, which generate functional hemangioblasts with high efficiency. CONCLUSION This 3D serum- and stromal-free microcarrier system is important for future clinical applications, with the potential of developing to a GMP-compatible scalable system.
APELIN promotes hematopoiesis from human embryonic stem cells. Blood 2012 JUN
Abstract
Transcriptional profiling of differentiating human embryonic stem cells (hESCs) revealed that MIXL1-positive mesodermal precursors were enriched for transcripts encoding the G-protein-coupled APELIN receptor (APLNR). APLNR-positive cells, identified by binding of the fluoresceinated peptide ligand, APELIN (APLN), or an anti-APLNR mAb, were found in both posterior mesoderm and anterior mesendoderm populations and were enriched in hemangioblast colony-forming cells (Bl-CFC). The addition of APLN peptide to the media enhanced the growth of embryoid bodies (EBs), increased the expression of hematoendothelial genes in differentiating hESCs, and increased the frequency of Bl-CFCs by up to 10-fold. Furthermore, APLN peptide also synergized with VEGF to promote the growth of hESC-derived endothelial cells. These studies identified APLN as a novel growth factor for hESC-derived hematopoietic and endothelial cells.
