Iranian homograft tissue processing

Tissue transplantation is a life-enhancing therapeutic modality for damaged or non-functioning tissues. In most cases, there is no alternative other than human tissue as replacement, and taking into account the ever-increasing demand for tissue grafts, it makes sense to set up an establishment in charge of human tissue procurement to meet local needs. A quality assurance system, clearly defined...

Homograft Immunity in Pregnancy

The effect of homograft sensitization of a mother against her fetuses has been studied. A female rabbit was repeatedly grafted from both members of a breeding pair. Their offspring should and do become objects of homograft sensitization induced in the female by grafts from the parents. After sensitization was established, fertilized ova were transplanted from the breeding pair to the sensitized...

Cellular Specificity in the Homograft Reaction

The present study offers direct evidence that cells from the regional lymph node draining first-set skin homografts in rabbits participate in the lymphoid infiltrate at distant sites of graft rejection. With the use of a newly devised method of injection, adequate amounts of tritiated thymidine could be confined to the reactive regional node, other dividing cells of the host remaining unlabeled...

Immature joint cartilage and the homograft reaction.

It is apparent from studies of the homograft reaction that cartilage is exceptional in that when it is transferred to another animal of the same species it does not provoke the same vascular and cellular responses that occur with most other tissues. In consequence, such cartilage transfers may survive for a long time in a viable state: instances of human grafts which remained healthy for as lon...
