Stem cells arise from the inner mass of the cell
Signalling factors trigger differentiation in stem cells
Genes that lead to the production of undifferentiated blood cells are activated
Signalling factors cause undifferentiated blood cells to produce red blood cells
Explanation:
Red blood cells are formed in the bone marrow. The precursor to the RBC is stem cell which is undifferentiated and pluripotent. The stem cell gets differentiated to form immature RBCs. Immature RBC then gets divided and becomes mature. Stem cell giving rise to RBC is called Haemoctytoblast. The process of erythropoiesis takes 2 days to form new red blood cells

Answer:
Taxol alters cytosolic calcium signaling by opening mitochondrial pores
Explanation:
Taxol is an antimitotic (i.e., cytotoxic) agent used in chemotherapy to kill cancer cells. Taxol is an antimitotic drug that has been successfully used in different types of cancer including ovarian cancer, breast cancer, pancreatic cancer, sarcoma, etc. Recently, it has been shown that Taxol may induce rapid cytosolic calcium (Ca2+) response by producing a decrease in mitochondrial membrane potential associated with the loss of mitochondrial Ca(2+). In consequence, it has been proposed that the side effects of chemotherapy might be associated with the action of cytotoxic agents such as Taxol which alters mitochondrial function and Ca(2+) signaling cascade.
