This is the  eleventh of a series of short videos on Low dose Medicine and in particular Cytokines. This video introduces the cytokine Granulocyte colony-stimulating factor (G-CSF or GCSF). Granulocyte colony-stimulating factor is a glycoprotein which stimulates the the proliferation and differentiation of hematopoietic progenitor cells from the bone marrow into granulocytes (white blood cells) and neutrophils.  G-CSF is produced by monocytes, macrophages, and neutrophils after cell activation and it is also produced by stromal cells, fibroblasts, and endothelial cells.  G-CSF triggers the reactivity and raises the sensitivity of the immune system, and it enhances the antibody-dependent cell mediated cytotoxicity of granulocytes against tumor cells.    More information about this and other health topics can be found in my books "Low Dose Medicine" and "Cure Without Side effects" by following these links: ►►►https://amzn.to/3Bbx8fd  ►►►https://amzn.to/36iaqDU To check the Low dose Medicine health kit follow this link:  ►►►https://kit.co/cureswithoutsideffect/low-dose-medicine  DISCLAIMER: Nothing contained in this video is intended nor can be taken  to diagnose, treat, or cure any disease.
