Specific fragments of vasostatin are disclosed. These fragments are of use in methods of stimulating the proliferation or survival of a hematopoietic cell exposed to a chemotherapeutic agent or irradiation. Methods of stimulating the proliferation or survival of a hematopoietic cell using these fragments are also disclosed. In one embodiment, methods are disclosed for stimulating the growth or survival of a hematopoietic stem cell with a fragment of vasostatin, in the presence of a growth factor.

Vasostatin as marrow protectant

Methods for inhibiting endothelial cell growth and angiogenesis, and suppressing tumor growth using calreticulin, fragments of calreticulin and variants of calreticulin are provided. Such methods are useful for the treatment of cancer and diseases associated with unwanted angiogenesis, for example chronic retinal detachment.
