Infantile Hemangioma Originates From A Dysregulated But Not Fully Transformed Multipotent Stem Cell
Infantile hemangioma (IH) is the most common tumor of infancy. Its cellular origin and biological signals for uncontrolled growth are poorly understood, and specific pharmacological treatment is unavailable. To understand the process of hemangioma-genesis we characterized the progenitor hemangioma-derived stem cell (HemSC) and its lineage and non-lineage derivatives. For this purpose we perform...
متن کاملNOTCH3 regulates stem-to-mural cell differentiation in infantile hemangioma.
Infantile hemangioma (IH) is a vascular tumor that begins with rapid vascular proliferation shortly after birth, followed by vascular involution in early childhood. We have found that NOTCH3, a critical regulator of mural cell differentiation and maturation, is expressed in hemangioma stem cells (HemSCs), suggesting that NOTCH3 may function in HemSC-to-mural cell differentiation and pathologica...
متن کاملPericytes from infantile hemangioma display proangiogenic properties and dysregulated angiopoietin-1.
OBJECTIVE Infantile hemangioma (IH) is a rapidly growing vascular tumor affecting newborns. It is composed of immature endothelial cells and pericytes that proliferate into a disorganized mass of blood vessels. We isolated pericytes from IH (Hem-pericytes) to test our hypothesis that Hem-pericytes are unable to stabilize blood vessels. METHODS AND RESULTS We injected pericytes in vivo, in com...
متن کاملInfantile Hemangioma: A Brief Review
Infantile hemangiomas as frequent infancy tumors have been a controversial issue of medical scientists worldwide. Their clinical aspects are various and their physiopathology is yet to be fully understood. Numerous publications outline the characteristics, causes, evolution possibilities and therapeutic approaches. Deciding whether to treat or not is the main question of this kind of pathology....
متن کاملMultipotential stem cells recapitulate human infantile hemangioma in immunodeficient mice.
Infantile hemangioma is a benign endothelial tumor composed of disorganized blood vessels. It exhibits a unique life cycle of rapid postnatal growth followed by slow regression to a fibrofatty residuum. Here, we have reported the isolation of multipotential stem cells from hemangioma tissue that give rise to hemangioma-like lesions in immunodeficient mice. Cells were isolated based on expressio...
