Model description:
In modern contract R&D there’s an unmet need for physiologically relevant human skin models. In order to determine whether the substance of interest is safe for human exposure (predict an adverse event), to identify the mode of action, to further identify the target group and for the risk assessment of therapeutics precise engineered tissue models are essential. Human skin and scar models are cultured human skin cells, which serve as an alternative for animal testing and mimic the human reaction in vitro as closely as possible. Geneusbiotech  offers a broad range of state-of-the-art human skin models (for investigating how compounds can interfere with normal skin homeostasis and disease) and skin tissue engineering expertise. The skin models can be adjusted to specific research needs.
We offer various models such as: 

1. Adipose and Dermis is derived MSC, Fibroblasts and Endothelial cells
2. Pigmented skin equivalents, Keratinocytes, Melanocytes and Fibroblasts 
3. Adipose layer equivalent-ASCs populated Hydrogel
4. Immune-competent skin containing Langerhans Cells (CD1a)
5. Scar models (Human Scar, Hypertrophic Scar & Keloid Model)

Read-out options:
