From: Co-transplantation with adipose-derived cells to improve parathyroid transplantation in a mice model
SVFs improved parathyroid transplantation survival and blood vessel assembly. a The parathyroid glands were hard to be distinguished from thyroid under normal white light in the rat, while 5-ALA sufficiently visualized the parathyroid gland pairs with red fluorescence under blue light illumination. b The long and short diameters of thyroid gland lobe were approximately 4 mm × 2 mm, while those of parathyroid gland was approximately 2 mm × 1 mm. LD, long diameter; SD, short diameter. c The thyroid glands were brownish red, and the parathyroid glands were smaller and lighter color. d Pathological examination confirmed the efficacy of 5-ALA methods to identify parathyroid. e 5-ALA was used to visualize the functional transplanted parathyroid grafts, which exhibited red fluorescence under blue light. f More blood vessels around the transplanted parathyroid tissues in the SVF group. g The survival rate of the SVF group was higher than that of the control group. h The serum PTH levels in the SVF group was 2-fold higher than those in the control group, n ≥ 5; *p < 0.05. i Quantification of vessel analysis throughCD31 IHC score calculation of parathyroid grafts in the SVF and control groups, n ≥ 5; **p < 0.01. j Representative hematoxylin and eosin staining and CD31 IHC staining of parathyroid grafts from the SVF and control groups
