On 19 January, co-founders Rick Klausner and Hans Bishop publicly launched an aging research initiative called Altos Labs, with $3 billion in initial financing from backers including tech investor Yuri Milner and Amazon founder Jeff Bezos. This is the latest in a recent surge of investment in ventures seeking to build anti-aging interventions on the back of basic research into epigenetic reprogramming. In December, cryptocurrency company Coinbase’s cofounder Brian Armstrong and venture capitalist Blake Byers founded NewLimit, an aging-focused biotech backed by an initial $105 million investment, with the University of California, San Francisco’s Alex Marson and Stanford’s Mark Davis as advisors.
The discovery of the ‘Yamanaka factors’ — four transcription factors (Oct3/4, Sox2, c-Myc and Klf4) that can reprogram a differentiated somatic cell into a pluripotent embryonic-like state — earned Kyoto University researcher Shinya Yamanaka a share of the Nobel prize in 2012. The finding, described in 2006, transformed stem cell research by providing a new source of embryonic stem cell (ESC)-like cells, induced pluripotent stem cells (iPSCs), that do not require human embryos for their derivation...
