Well, not exactly. In one of my wildest fantasy, we live in a world where humans can generate anatomical parts that stop working or have loss in accident or injuries. Norriton, PA, Tengion brings us one step closer to this fantasy. Tengion is a biotech firm focused in tissue regeneration in diseased or damaged organs. They’ve recently raised $33 million in third round funding with investors such as Deerfield Partners, Bain Capital, Johnson & Johnson Development, HealthCap, Quaker Bio Ventures, Oak Investment Partners, L Capital Partners, Horizon Technology Finance and Oxford Finance.


Currently, they’re working on regrowing bladder tissue to treat patients with spinal bifida or spinal-cord injuries. This technique was designed by Dr. Atala of Wake Forest University’s Institute for Regenerative Medicine (IRM). You can read more about Dr. Atala’s technique here. The above picture shows Dr. Atala and what the bladder tissue that he grows look like.

As many of you still remember, we’re able to grow “simple” tissue which doesn’t have complex biological functions as in the much publicized ear on a nude mouse. So what Tengion is attempting to do is to grow complex tissue of organs which are involved in complex biological functions such as the bladder.

Biologically speaking, we know that lizards and some other animals are able to regrow limbs after they are loss. If they are able to do it, theoretically, we should be able to do it as well (I know that does sound like something out of a Spiderman comic), but I really do believe that to be true someday. Cell growth are stimulated by the proper hormones and stimulant being released. Some examples have been seen in the regrowth nervous tissues in which cells know where they are suppose to be and they migrate there. It is not too far to see that if could potentially grow another arm if it is loss.
