Patient derived xenografts (PDX) are models of cancer where the tissue or cells from a patient's tumor are implanted into an immunodeficient or humanized mouse. [1] It is a form of xenotransplantation. PDX models are used to create an environment that allows for the continued growth of cancer after its removal from a patient.

Xenotransplantation (xenos- from the Greek meaning "foreign" or strange [1][2]), or heterologous transplant, is the transplantation of living cells, tissues or organs from one species to another. [3] . Such cells, tissues or organs are called xenografts or xenotransplants.

2024年12月23日 · Xenografts are engrafted tissues or organs derived from a different species than that of the recipient. Learn more about their applications in wound treatment and oncology.

2022年10月24日 · The main difference between allograft autograft and xenograft is that allograft is the transplantation of tissue from one donor to host in the same species, autograft is the transplantation of tissue from the same person, whereas xenograft is the transplantation of tissue from one donor to the host of a different species.

Xenotransplantation is any procedure that involves the transplantation, implantation or infusion into a human recipient of either live cells, tissues, or organs from a nonhuman animal source, or...

Xenografts are grafts that are derived from the inorganic portion of bone from a different species (ie, bovine and porcine). Xenografts share many of the advantages of allografts, but debate exists concerning their efficacy compared with allografts.

2024年4月3日 · Xenografts allow researchers to study diseases and test treatments in live organisms without initial human trials.

Xenotransplants, or xenografts, are viewed as one solution to the growing problem of the inadequate supply of human organs and as a source of cells, tissues, and organs that show promise for treating a variety of human diseases.

This review serves as a brief discussion of the recent progress in xenotransplantation research, particularly as it concerns utilization of porcine heart, renal, and liver xenografts in clinical practice.

Xenografts are grafts taken from a donor of another species. Currently, anorganic, bovine-derived, equine-derived bones, and coral skeleton have been marketed for periodontal regenerative and implant therapy.
