Bioartificial primarily vascularized tissue matrix, and bioartificial primarily vascularized tissue, method for the production and use of the same

A method of producing a bioartificial primarily vascularized autologous, allogenic or xenogenic tissue matrix, the method comprising the steps:

• extracting tissue from one of a human body and an animal body, wherein the extracted tissue includes at least one functioning vessel branch connected as part of the extracted tissue, wherein the at least one vessel branch includes a supplying artery and a discharging vein, and
• acellularizing at least a portion of the extracted tissue, resulting in the tissue matrix comprising a matrix of the at least one vessel branch,
• wherein the at least one vessel branch enables the provision of at least one of nutrients, minerals, and oxygen.
