Biological & immunological validation

Human skin structure and its resident immune cells are maintained for 7 days

Genoskin

Since we use real human skin to generate HypoSkin®models, they have the same structure and composition as in vivo human skin. Hematoxylin & Eosin staining confirms the preservation of tissue and cellular structures across all three skin layers (epidermis, dermis, and hypodermis). Visual examination reveals a mature stratum corneum, a dermal-epidermal junction mirroring real human skin, and intact basal layers and rete ridges. Notably, the images also demonstrate the sustained integrity of HypoSkin® for a duration of up to 7 days.

Presence of skin-resident immune cells at 7 days

Genoskin’s proprietary technology enables the maintenance of all skin-resident immune cells for over a week during experimentation.

immune cells are characterized in HypoSkin using the MANTIS spatial biology platform

The MANTIS® spatial biology platform enables visualization of immune cell locations within the skin layers and their relative proximity to other cells in HypoSkin® models. The Myeloid Panel is shown here where localization of mast cells, langerhans and dentritic cells are demonstrated.

The figure on the right illustrates the presence of the various cell populations present in the skin over 10 days of culture.

Functional and activatable skin-resident human immune cells

HypoSkin® remains fully living and immunocompetent throughout a 7-day experimental period. This enables longitudinal secretome analysis for evaluating the toxicity and efficacy of therapeutic and chemical compounds.

Injectable human skin model

HypoSkin® is a human skin model that provides the closest substitute for in vivo injection of compounds. Whether your compound is meant to be subcutaneously or intradermally injected, you can use HypoSkin® model to assess it’s efficacy or toxicity.
