groups of cells that adhere together forming a mass
Cell aggregates, also known as cell clusters, are groups of cells that adhere to each other, forming a mass. These aggregates can occur naturally in the body, such as in the formation of tissues and organs, or can be created in a laboratory setting for research purposes. In the context of hair and alopecia, cell aggregates might be studied to understand how hair follicles develop and how they can be regenerated or repaired.
