Self-renewing hematopoietic stem/progenitor cells (HSPCs) produce blood cells of all lineages throughout life. Phosphatase and tensin homolog (PTEN), a tumor suppressor that antagonizes phosphatidylinositol 3-kinase (PI3K) signaling, is frequently mutated in hematologic malignancies such as bone marrow failure and leukemia. We set out to investigate whether Pten is required for hematopoiesis.

Angiogenesis, the emergence of vessels from an existing vascular network, is pathologically associated with tumor progression and is of great interest for therapeutic intervention. PTEN is a frequently mutated tumor suppressor and has been linked to the progression of many types of tumors, including hemangiosarcomas in zebrafish. Here, we report that mutant zebrafish embryos lacking functional Pten exhibit enhanced angiogenesis, accompanied by elevated levels of phosphorylated Akt (pAkt).
