Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Hundreds of people came to our hospital requesting upper blepharoplasty every year. Taking advantage of the discarded soft tissue in the blepharoplasty surgery, samples of bilateral pretarsal fat can be easily obtained from patients of various ages. This study is designed to objectively evaluate the age-related changes of the preadipocytes in human periorbital adipose tissue regarding their proliferation and differentiation capability.
The adipose samples taken during the surgery are sent to the lab immediately to separate the preadipocytes from the specimens. Their number is estimated under the microscope, and then the cells are cultured in vitro to evaluate their proliferation and differentiation capability. Proliferation is assessed by counting the number of preadipocyte everyday for 7 days, and differentiation is assessed by Glycerol-3-phosphate dehydrogenase (GPDH) assay.
A linear regression analysis is used to analyze correlations of the parameters with age. Moreover, by dividing the subjects who had their periorbital fat sampled during upper blepharoplasty operation into three age groups, the parameters are compared with ANOVA test. Therefore, the age-related changes of the proliferation and differentiation capability of the preadipocytes in human periorbital adipose tissue can be concluded.
