Spheroid cell culture of human skin-derived precursors
Scope of the method
- Human health
- Basic Research
- Translational - Applied Research
- In vitro - Ex vivo
- Human derived cells / tissues / organs
- tree-dimensional spheroid culture
- hepatic differentiation
- skin stem cells
For the generation of the human skin-derived precursors (hSKP) spheroids, ultra-low attachment 96-well plates, cell-repellent (Greiner) are used. hSKP cultured on tissue culture plates are detached with trypple (5 minutes) and collected in a tube. After centrifugation, hSKP are counted at the Burker chamber and seeded at 2,000 cells per well. The 96-well plates are placed on an orbital shaker, shaking at 40 rpm overnight in a humidified incubator. The outer wells are filled with PBS to reduce evaporation of cell culture medium. The day after, hSKP aggregates of approximately 200-250 µm diameter size are formed. Culture medium is refreshed twice in a day every 3 days to allow complete medium replenishment.

Pros, cons & Future potential
- Emulation of 3D cell organization, simple method, applicable to many cell types.
- Spheroid formation has been shown to enhance anti-inflammatory effects, augment tissue regenerative and reparative effects, facilitate differentiation potentials of multiple lineages, improve stemness properties of adult stem cells.
- Spheroid handling and transfer step (e.g. spheroids may be easily lost by aspiration with pipette during refreshment of cell culture medium).
- Presence of a necrotic core inside the sphere that could lead to poor cell viability in long-term culture.
Since spheroid generated from mesenchymal stem cells exert strong anti-inflammatory and immuno-modulatory effects, they could be employed in regenerative medicine and autoimmune diseases.
