Definitions
- Hair follicles are known to contain a well-characterized niche for adult stem cells including the bulge containing epithelial and melanocytic stem cells. Stem cells in the hair bulge can generate the interfollicular epidermis, hair follicle structures and sebaceous glands. The budge epithelial stem cells can also reconstitute in an artificial in vivo system to a new hair follicle. It has been known that transplanting hair follicle stem cells in balding scalp results in increase hair density and may promote new formation of hair follicles. Stem Ceel Investig. 2017, 4:58.
- the result of the transplantation was somewhat limited as the amount of the transplanted stem cells was limited to the amount obtained from a patient through a physical separation.
- a method and a system that allows culturing such stem cells in vitro in particularly in 3D.
- adjusting planted scalp conditions for better settlement of the stem cells would help the effectiveness of such treatment.
- 3D cell culture techniques have led to the creation of more predictive in vitro cell models for numerous applications including cancer research, drug discovery, neuroscience and regenerative medicine.
- Cells naturally grow and differentiate in three dimensional environments.
- Cells in their natural environment have constant interactions with extracellular matrix proteins (ECM) and other cells, regulating complex biological functions like cellular migration, apoptosis, or receptor expression. Most of these interactions are lost, or significantly reduced, in traditional 2D cell cultures.
- ECM extracellular matrix proteins
- Advanced 3D cell systems allow researchers to bridge the gap between classical 2D cell culture and in vivo animal models.
- advanced 3D cell culture methods such as tumor spheroids, stem cell organoids and tissue engineering via 3D bioprinting have been implemented to more closely model real in vivo cellular responses.
- 3D cell culture models can be divided into two main categories: 1) scaffold-based methods using animal derived/synthetic hydrogels or structural 3D scaffolds and 2) scaffold-free approaches using freely floating cell aggregates termed spheroids.

- organoid which is herein defined as any 3D mass of cells or 3D cell models including conventional organoid and spheroid as well as tissue.
- Such 3D cell models have many benefits over conventional two-dimension cell structures.
- 3D organoid is physiologically more like actual biologic organ or tissue and can be used for drug discovery or screen or medical treatments such as cell therapies, etc.
- 3D organoid can be used for creating micro physiological systems or organs-on-chips to study difficult clinical problems and development of potential treatments.
