Concise review: tissue-specific microvascular endothelial cells derived from human pluripotent stem cells

Area of Science:

• Endothelial cell biology
• Stem cell differentiation
• Regenerative medicine

Background:

• Endothelial cells (ECs) exhibit significant tissue-specific heterogeneity.
• ECs are crucial for tissue regeneration and homeostasis.
• Derivation of tissue-specific microvascular endothelial cells (TS-MVECs) from human pluripotent stem cells (hPSCs) offers potential for novel applications.

Purpose of the Study:

• To review current techniques for deriving hPSC-derived TS-MVECs.
• To discuss strategies for directing hPSC-EC differentiation toward tissue-specific fates.
• To explore applications in regenerative medicine and in vitro modeling.

Main Methods:

• Review of existing literature on hPSC-EC differentiation protocols.
• Analysis of strategies for achieving tissue specificity in hPSC-derived ECs.
• Discussion of coculture, directed differentiation, and direct reprogramming.

Main Results:

• Established hPSC-EC differentiation protocols exist.
• Methods to impart tissue specificity are being developed.
• Coculture, directed differentiation, and reprogramming are key strategies.

Conclusions:

• hPSC-derived TS-MVECs hold promise for regenerative medicine and in vitro disease modeling.
• Further refinement of differentiation protocols is needed to enhance tissue specificity.
• Integration of ECs and parenchymal cells is a promising avenue for generating functional TS-MVECs.
