Abstract:
The use in the medical-surgical field of biomaterials based on hyaluronic acid derivatives, optionally in association with natural, synthetic or semisynthetic biopolymers, for suppressing the angiogenic process associated with tumour proliferation (in primary and secondary tumours) is disclosed.
Abstract:
The present invention relates to organotypic cultures of epidermal cells and their uses for the screening of pharmaceutical and cosmetic agents. Specifically, means for the improvement of the long-term stability of said cultures are disclosed. Thus, the present invention contemplates a skin equivalent comprising (a) a dermal equivalent comprising a matrix comprising (i) nonwoven viscose fabric and (ii) fibroblasts and (b) keratinocytes. Moreover, the present invention contemplates a method for manufacturing said skin equivalent and a method for screening of agents capable of influencing skin, such as a therapeutic or cosmetic agent.
Abstract:
Described is an immortalized mammalian skin keratinocyte line, preferably HaCaT, stably transfected with a vector capable of expressing a nucleic acid sequence encoding at least one growth factor and/or activated EGF receptor. Furthermore, a skin equivalent and an in vitro toxicity assay making use of this immortalized mammalian skin keratinocyte line is described.
Abstract:
The present invention provides skin equivalents comprising human epidermal stem cells which are specifically labeled. The labeling is carried out with a marker capable of labeling slowly proliferating cells, e.g. iododeoxyuridine or PKH26. Particularly, the invention provides skin equivalents comprising labeled epidermal stem cells. The invention also provides corresponding uses and methods of using such cultures, e.g. in the fields of research and medical treatment of skin diseases.
