Interestingly, the regenerative ability of any given tissue can be very high, medium, or low/negligible. For example, the liver can regenerate after removal of ~75% of the tissue. In infants, digit tips can often be regenerated. Our skin has a reasonable regenerative capacity, albeit with fibrotic scarring. Finally, many of our tissues cannot be regenerated at all, such as entire limbs, cartilage in...
