    摘要: The present invention relates to a biological material having a matrix which contains at least one derivative of hyaluronic acid on which endothelial cells, glandular cells such as islets of Langerhans and liver cells, skin adnexa, germinative cells of hair bulbs, and kerinatocytes are grown, optionally in presence of a medium treated with fibroblasts or in a co-culture with fibroblasts. A process for the production of said biologic materials and the use of such materials for human and veterinary applications such as cardiovascular and oncological surgery, in connection with transplants, for enhancing the biological process of tissue vascularization and for aesthetic use, and also for the screening of medicaments or toxic substances and as a support in the process of gene transfection. The biological material is based on an efficacious cell culture and a biocompatible and biodegradable three-dimensional matrix containing a hyaluronic acid derivative.
