Having a sample of your young bone marrow around 40 years from now could have enormous biomedical ramifications. I'm not just talking about cryonics. An autologous bone marrow sample could be used anytime to "re-boot" the immune system, thereby protecting you against a host of immune diseases and cancers from the day you donated it. I also strongly suspect that decades from now young stem cells could form the basis of radical therapies for reversing aging. Protection against cancers today requires that bone marrow cryopreservation be reversible in real-time. Can anyone confirm that bone marrow can in fact be reversibly cryopreserved with today's technology? The second, more speculative possibility will probably be more tolerant of imperfect preservation since only stem cell nuclei may be required. I have been interested in doing this for some time, even if it costs a few K. I am not certain how to proceed. Two (not necessarily independent) ingredients are required. First, you must find a clinic to remove the bone marrow (a painful procedure, I'm told). Then you have to find a trustworthly institution to store it. I personally think cryonics organizations are better candidates for the latter than fly-by-night tissue banks. Then again, there is something to be said for not having all your eggs in one basket. Several years ago there was a piece in the Immortalist about a firm offering to remove and store bone marrow with just the above applications in mind. Does anyone remember the magazine issue, or the company name? Are there any further comments (Steve H., Mike D.?) about the soundness of this strategy. --- Brian Wowk Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=2481
