Abstract
A biological material comprising two components is provided containing a first component comprising alternatively (1) a culture of autologous or homologous bone marrow stem cells partially or completely differentiated into specific connective tissue cellular lines or (2) a sole extracellular matrix free from any cellular component secreted by the specific connective tissue cellular lines; and a second component containing a three-dimensional biocompatible and biodegradable matrix consisting of a hyaluronic acid ester having a degree of esterification comprised between 25 and 100%. The specific tissue cell lines are selected from fibroblasts, osteoblasts, myoblasts, adipocytes, chondrocytes and endothelial cells. The biological material is suitable for use as a dermal substitute in cutaneous lesions as well as repairing damaged connective tissue.
