Abstract:


Hematopoiesis is the process which generates all the mature blood cells from the rare pool of Hematopoietic stem cells (HSCs). Asymmetric cell division of HSCs provide it dual capacity for self-renewal and multi-potent differentiation. Hematopoiesis is a steady state process in which mature blood cells are produced at the same rate at which they are lost, establishing a homeostasis. HSCs are regulated through their environmental niche, cytokine signalling, and the orchestrated activities of various transcription factors. However, there is very little information available about the signal transduction events that regulate HSC function; in particular, the effects of bioactive lipids and lipid mediators are not well understood. Recent studies have added an important aspect of this process, introducing the role of lipids in cell fate decisions during hematopoiesis. The mechanisms of bioactive lipids and their derivatives have been studied extensively in signal transduction and various other cellular processes.

This review focuses on various categories of lipids and their regulatory mechanisms in HSCs and their comment into different blood cells. Moreover, we also discuss the role of lipid signalling specifically in megakaryocyte and platelets.
