The discussion centers on the impossibility of humans regrowing lost limbs, contrasting human biology with that of species like newts and salamanders that can regenerate. Key points include the complexity of embryonic development, which occurs within the first eight weeks of gestation, and the crucial role of gene expression and morphogenetic fields in limb formation. Current advancements in regenerative medicine, such as products from ACell Inc and LifeCell, aim to stimulate regeneration but do not replicate the full limb growth process. The consensus is that while prosthetic technology may advance, the biological regrowth of limbs in humans remains unlikely due to the inherent differences in adult and embryonic cellular contexts.
PREREQUISITESThis discussion is beneficial for biologists, medical researchers, and bioengineers interested in regenerative medicine, prosthetics, and the biological limitations of human limb regeneration.

Ruslan_Sharipov said:If you reconstruct bones, and muscles, and blood vessels, and nerves, and joints, and skin, then your item LOOKING like a limb will SERVE as a limb.

Borek said:Do you have any evidence to support a claim that it is currently possible?
