In conclusion, HSC ageing is characterised by reduced self-renewal, myeloid and platelet HSC skewing, and expanded clonal haematopoiesis that is considered a preleukaemic state. The underlying molecular mechanisms seem to be related to increased oxidative stress due to ROS accumulation and DNA damage, which are influenced by both cell- and cell non-autonomous mechanisms such as prolonged exposure to infections, inflammageing, immunosenescence, and age-related changes in the HSC niche. Thus, HSC ageing seems to be multifactorial and we are only beginning to connect all the dots.
The Price of Progress or the Waste of Regulation?

The average cost of delivering a new therapy from laboratory to clinic is increasing at a fast pace, more than doubling since the turn of the century according to some studies, to stand at 2.5 billion or more. This is not driven by the work of research and development becoming more expensive: if anything, the price of the tools of biotechnology is in free fall, even as capacity increases by orders of magnitude. Biotechnology has gone through, and is still going through, its own echoed version of the computing revolution of recent decades. A mix of advances in computational power and materials science means that a graduate student of today requires six months of lab time and a few tens of thousands in funding to accomplish what would have ta...
