Objective  To investigate the way to culture human parathyroid cells and to investigate its secretory function. Methods  After digested by collagenase, parathyroid cells were isolated to get the original generation cells, then the cells were cultured and passaged, and morphological changes of original generation cells and passage cells were observed on every day. The parathyroid hormone(PTH) level secreted by the original generation cells and passage cells were measured on the 1st, 5th, 10th, 15th, and 20th day(original generation cells only) respectively. Results  The cellular morphology was complete after digestion. On the 2nd day, most of the parathyroid cells had adhered and spreaded, on the 3rd day, all cells had spread. There was no very obvious changes on these cells after cultured for 4-15 days. From 16 to 20 days, some parathyroid cells went senescence. On the 1st day, all of the passage cells, which were fusiform and little bigger than those of the original generation cells, had adhered and spreaded. From 2 to 15 days, there was no very obvious changes. The concentration of PTH in original generation cells begin to decreased significantly on the 10th day (P < 0.01). The concentration of PTH in passage cells were all lower than those of original generation cells at the same corresponding time, but there were no significant difference on the PTH level on 5th day and 1st day, 10th day and 5th day, 15th day and 10th day in passage cells (P > 0.05). Conclusion  Parathyroid cells which were cultured within 10 days possess well morphologic structure and have the strongest secretory function. Although the passage cells still possess secretory function, it is greatly inferior to original generation cells. At last, we consider that original generation cells cultured within 10 days can be regarded as the source of allogeneic cell transplantation.
