Bone morphogenetic proteins and vascular differentiation: BMPing up vasculogenesis

Area of Science:

• Developmental Biology
• Vascular Biology
• Regenerative Medicine

Background:

• Vasculogenesis, the formation of new blood vessels, occurs in embryos and adults.
• This process is crucial for tissue repair in conditions like myocardial infarction.
• Embryonic signaling pathways, such as BMP signaling, are reactivated in adult vasculogenesis.

Purpose of the Study:

• To explore the role of BMPs in embryonic and adult vasculogenesis.
• To investigate the interaction between BMP signaling and other pathways like VEGF.
• To understand the function of novel BMP modulators, such as BMPER, in vascular cells.

Main Methods:

• Utilizing gain and loss of function models to study BMPs.
• Analyzing the expression of molecules like BMPER in vascular cells.
• Investigating the interplay between BMP and VEGF signaling pathways.

Main Results:

• BMPs were found to stimulate vasculogenesis in both embryonic and adult contexts.
• BMP signaling interacts with other key pathways, including VEGF signaling.
• Novel molecules like BMPER, expressed in vascular cells, modulate BMP activity.

Conclusions:

• BMPs play a significant role in stimulating vasculogenesis throughout life.
• Understanding BMP and related signaling pathways is key to comprehending adult blood vessel formation.
• Further research into molecules like BMPER may reveal new therapeutic strategies for vascular diseases.
