粒细胞集落刺激因子

总览

粒细胞集落刺激因子 (G-CSF) 是 CSF 糖蛋白家族的成员,其功能调节造血细胞的增殖、分化和功能。它是参与中性粒细胞生成和刺激造血祖细胞形成粒细胞集落的关键细胞因子 (Metcalf & Nicola)。G-CSF 可引起一系列效应,包括暂时降低 SDF-1 表达 (Petit et al.)、激活裂解 VCAM-1 的金属蛋白酶 (Levesque et al.) 以及从交感神经系统释放去甲肾上腺素 (Katayama et al.),从而导致造血干细胞从骨髓释放或动员到外周。 G-CSF受体在多种造血细胞中表达,包括髓系定向祖细胞、中性粒细胞、粒细胞和单核细胞。除造血细胞外,G-CSF还在心肌细胞、神经元细胞、间皮细胞和内皮细胞中表达。G-CSF与其受体结合可激活JAK/STAT、MAPK、PI3K和AKT信号转导通路。

实验数据

(A) The biological activity of Human Recombinant G-CSF was tested by its ability to promote the proliferation of mouse NFS-60 cells. Cell proliferation was measured using a fluorometric assay method. The EC50 is defined as the effective concentration of the growth factor at which cell proliferation is at 50% of maximum. The EC50 in the above example is 0.053 ng/mL.
(B) 1 µg of Human Recombinant G-CSF was resolved with SDS-PAGE under reducing (+) and non-reducing (-) conditions and visualized by Coomassie Blue staining. Human Recombinant G-CSF has a predicted molecular mass of 18.8 kDa.

Direct induction of haematoendothelial programs in human pluripotent stem cells by transcriptional regulators. I. Elcheva et al. Nature communications 2014 jul

Abstract

Advancing pluripotent stem cell technologies for modelling haematopoietic stem cell development and blood therapies requires identifying key regulators of haematopoietic commitment from human pluripotent stem cells (hPSCs). Here, by screening the effect of 27 candidate factors, we reveal two groups of transcriptional regulators capable of inducing distinct haematopoietic programs from hPSCs: pan-myeloid (ETV2 and GATA2) and erythro-megakaryocytic (GATA2 and TAL1). In both cases, these transcription factors directly convert hPSCs to endothelium, which subsequently transform into blood cells with pan-myeloid or erythro-megakaryocytic potential. These data demonstrate that two distinct genetic programs regulate the haematopoietic development from hPSCs and that both of these programs specify hPSCs directly to haemogenic endothelial cells. In addition, this study provides a novel method for the efficient induction of blood and endothelial cells from hPSCs via the overexpression of modified mRNA for the selected transcription factors.
