【Abstract】Objective To study the influence of transplantation of cultured parathyroid cells on the survival of the allografts in rats.
Methods Parathyroid cells digested with collagenase and trypsin were cultured and transplanted under the left renal capsule. The survival time of the allografts was recorded and the allografts were examined by transmission electron microscopy.
Results In fresh parathyroid cells group, the mean survival time was (9.25±3.45) days. While in cultured parathyroid cells group, the survival time was (46.25±7.44) days (P＜0.01). During the 50 days of observation, serum calcium and PTH remained normal in 6 of 8 rats. There were intact parathyroid cells in the allografts which had abundant rough endoplasmic reticula,mitochondria and secretory granules.
Conclusion Transplantation of cultured parathyroid cells in rats can prolong the survival time of allografts and is a potent way to cure hypoparathyroidism.
