A significant immune response to the xenogenic

Methods: The in vitro matured slaughterhouse derived sheep oocytes were subjected to Intracytoplasmic Sperm Injection (ICSI) with epididymal, testicular, and xenogenic
Scaffolds including xenogenic
bone mineral , poly(DLlactic-co-glycolic acid) (PLGA) , HA/[beta]-TCP granula , and processed bovine cancellous bone (PBCB) matrices  have been successfully vascularized with surgical angiogenesis skills, allowing transplantation to defect sites.
The use of xenogenic
small intestinal sub mucosa as biomaterials for Achilles tendon repair in a dog model.
Past efforts at improving periodontal regeneration included xenogenic
(from a different species) bone particle graft using growth factors, but the clinical results were generally unsatisfactory, said the researchers.
cells (from non-human animal species) could also be used, but would present additional risks, such as the transmission of zoonotic diseases.
The study examining the effects of a systematic administration of either rat (allogenic) or human (xenogenic
) bone marrow stem cells administered to laboratory rats one day after their simulated strokes found "significant recovery" of motor behavior on the first day.

According to Parolini, cells delivered via intra-peritoneal transplant, regardless of the cells being allogenic or xenogenic
(host's own cells or from another individual respectively), the procedure resulted in a significant anti-fibrotic effect on the lab animals.
While polymer and xenogenic
scaffolds have been used, a number of questions have arisen concerning the viability of the resulting constructs.
