Thanks to its expertise in cellular and tissue engineering, Bioalternatives has developed in vitro or ex vivo study models that are suitable for analyzing the interactions between microbiota and skin:

  • Isolated bacterial culture (Staphylococcus aureus, Staphylococcus epidermidis, Propionibacterium acnes)
  • infection experiments with the HSV-1 virus ( Herpes simplex virus type I)

Co-culture:
- bacteria on 2D skin models (keratinocytes, fibroblasts, sebocytes, etc.)
- bacteria on 3D skin models (explants, reconstructed epidermis, etc.)

Both the impact of compounds or formulations on the development of bacteria and the influence of bacteria on cutaneous response can be assessed by these models.

Bioalternatives offers a panel of solutions for the evaluation of:

  • Bacterial viability
  • Quantification of bacterial colony (CFU)
  • Determination of bacterial load (qPCR (Taqman) or viral load
  • Bacterial adhesion on 3D models (explants, reconstucted epidermis)
  • Antimicrobial activity of compounds or formulations
  • Biological response of 2D or 3D models (differentiation, inflammation and immune response)

BIOalternatives immortalized a human sebocyte cell line (SEBO662), which responds to lipogenic stimulations and which can be used to select potential inhibitors.

BIOalternatives immortalized a human sebocyte cell line (SEBO662), which responds to lipogenic stimulations and which can be used to select potential inhibitors. This cell line was genetically modified in order to express a functional receptor to androgens (AR), as in the sebaceous gland. In this model, active androgens (dihydrotestosterone (DHT) or testosterone), tested alone in a non-supplemented basal medium, induce strong specific responses including the expression of androgen-sensitive genes but also the induction of a sebocyte differentiation program and lipid synthesis and storage.
From this work resulted a wide range of new cell based assays useful for the selection and evaluation of anti-androgen compounds or pro and anti-seborrheic compounds (acne, oily skin, dry skin, alopecia and hirsutism).

in vitro pharmacological solutions for the testing of psoriasis therapies

BIOalternatives research on psoriasis has been aiming at the development of in vitro models of keratinocyte inflammation. After analyzing the effects of conditioned media from LT clones on keratinocytes, we have analyzed the cytokine content of these media and screened a library of more than 40 cytokines for their responsiveness in keratinocyte cultures and also screened cytokine associations. These studies led to the identification of a cytokine mix (association of 5 cytokines; Patent # WO2006063864 A3) that induces a strong synergistic effect on keratinocytes in culture.
BIOalternatives offers various standard assays to select psoriasis targeting compounds and to characterize their effects at the major stages of the physiopathology.

BIOalternatives developed and validated an ex-vivo model of human hair follicle suitable for investigating the effect of compounds on:
• the stimulation/ inhibition of hair growth,
• the survival rate increase in cell cultures (anti apoptosis, anti-hair loss focus),
• The hair pigmentation.

These parameters can be analyzed by morphometric techniques (hair elongation and viability measurement) but also through complex molecular approaches: gene expression (dedicated PCRarrays or full genome profile, immunohistochemistry) or histology as special staining e.g. Fontana Masson for pigmentation.

Cell migration is commonly assessed using the scratch assay which measures the movement of cells into an artificial wound made on a confluent cell monolayer to create a cell-free area. As an alternative to the scratch assay which has high variability, the Oris™ Cell Migration Assay allows the formation of homogeneously sized cell-free areas into which migration can occur without releasing factors from dead cells or damaging the underlying extracellular matrix.
