Histological analysis of the subcutaneous implantation sites in immunodeficient mice, hematoxylin–eosin, scale bar—100 µm. A, B, C The capsule (*) around the implanted decellularized matrix (highlighted with dotted line) consisted of separate foci inside or around laser-formed wells. B, D, F The tissue around the cartilage construct (highlighted with dotted line) contained full-blooded vessels. The implant was infiltrated with minor areas of immune cells around the laser-formed wells
