From: Natriuretic peptides improve the developmental competence of in vitro cultured porcine oocytes
Detected natriuretic peptides concentrations in single follicles, classified according to the cleavage potential after in vitro fertilization with COCs coming from such follicles. a The single COCs in vitro culture model. b, d The concentrations of BNP, CNP in the follicular fluid of cleaved embryos (n = 6) and non cleaved embryos by culturing individually COCs from Single follicle in vitro and PA. c, e The concentrations of BNP, CNP in the follicular fluid of cleaved embryos (n = 9) and non cleaved embryos by culturing individually COCs from Single follicle in vitro and IVF. f, g The mean concentrations of BNP and CNP induced from b-e, in which the data from those were divided into three parts, the non-cleaved-low, the cleaved and the non-cleaved-high, as they were compared with the mean value. At least three follicles were examined at each time point for each experiment. The bars show the mean ± SEM of data from three independent experiments. Different columns with various superscript letters differ significantly (P < 0.05)
