Another proposed life extension technology would combine existing and predicted future biochemical and genetic techniques. SENS proposes that rejuvenation may be obtained by removing aging damage via the use of stem cells and tissue engineering, removal of telomere-lengthening machinery, allotopic expression of mitochondrial proteins, targeted ablation of cells, immunotherapeutic clearance, and novel lysosomal hydrolases.[71] While many biogerontologists find these ideas "worthy of discussion"[72][73] and SENS conferences feature important research in the field,[74][75] some contend that the alleged benefits are too speculative given the current state of technology, referring to it as "fantasy rather than science".[3][5] |
