26 Aug What is human placenta?
The human placenta is the membraneous vascular organ that develops in female mammals during pregnancy, lining the uterine wall and partially enveloping the foetus, to which it is attached by the umbilical cord.
The organ proliferates cells from merely one single ovum to over 60 trillion cells to form a complete foetus in 10 months. Interestingly, the placenta itself is also generated from an oval cell V placenta, and foetuses share the same origin. In proliferating foetal cells, the placenta synthesizes and secretes various Growth Factors and Cytokines, indispensable to foetal growth, through the course of gestation.
Deficiency in Growth Factors and Cytokines causes ageing. An infant’s body continues to generate huge quantities of Growth Factors and Cytokines after birth. It needs them to grow and to build up a post-natal immune system.
However, as one grows and gets older, the necessity of these substances lessens drastically and the body naturally ceases the synthesis of these mitogenic substances. This process is called ageing. Without these elements, the body starts to get old; skin colour darkens, age spots appear, wrinkles deepen, complexion worsens and ailments and sickness would ensure.
