Abstract Mammalian preimplantation embryo development is a complex sequence of events. This period of development is sensitive to oxygen (O2) levels that can affect various cellular processes. We compared the influence of O2 tension by culturing embryos either in normoxic (20% O2) or physiological hypoxic (6% O2) conditions. or sequential low O2 concentration starting with 6% O2 until... https://fitnessgravesyardes.shop/product-category/pivot-ramp/
