Did you mean Microenvironment?

Glossary Microenvironment

localized environment surrounding cells or tissues

The term "microenvironment" refers to the specific, localized environment surrounding cells or tissues, including factors like nutrients, oxygen levels, and signaling molecules. In the context of hair and alopecia, the hair follicle microenvironment includes the cells, extracellular matrix, and biochemical signals that influence hair growth and health. Understanding this microenvironment is crucial for developing treatments for hair loss conditions.

community Polydopamine Synergizes with Quercetin Nanosystem to Reshape the Perifollicular Microenvironment for Accelerating Hair Regrowth in Androgenetic Alopecia.

11 upvotes 2 years ago

A quercetin-encapsulated and polydopamine-integrated nanosystem (PDA@QLipo) shows promise for treating androgenetic alopecia by reshaping the perifollicular microenvironment, outperforming minoxidil in hair regeneration. The nanosystem promotes cell proliferation, hair follicle renewal, and recovery by scavenging reactive oxygen species and enhancing neovascularity.
