New models to study vascular mural cell embryonic origin: implications in vascular diseases

Area of Science:

• Vascular Biology
• Developmental Biology
• Cell Biology

Background:

• Vascular mural cells, smooth muscle cells (SMCs) and pericytes, are crucial for blood vessel formation and function.
• The diverse embryonic origins of SMCs and pericytes are increasingly recognized as key factors influencing vessel properties.
• Heterogeneities in mural cell origins may contribute to regional differences in vascular disease susceptibility.

Purpose of the Study:

• To review the role and regulation of mural cells during vascular development, focusing on embryonic origins.
• To examine the link between mural cell origin heterogeneity and vascular disease.
• To discuss novel model systems for studying mural cell development and disease implications.

Main Methods:

• Literature review of vascular biology and developmental studies.
• Analysis of evidence connecting mural cell origins to disease.
• Discussion of recent advances in in vitro derivation from human pluripotent stem cells and zebrafish models.

Main Results:

• Mural cell origins significantly influence vascular development and function.
• Specific origins of SMCs and pericytes are associated with distinct disease susceptibilities.
• In vitro stem cell differentiation and zebrafish models offer powerful tools for investigation.

Conclusions:

• Understanding mural cell origin diversity is essential for comprehending vascular disease.
• New model systems are critical for advancing research in this area.
• Discoveries hold significant medical relevance for disease modeling and therapeutic strategies.
