Do human lungs make blood? Here's what a popular study says
It is a basic principle in biology- blood is made in the bone marrow. It's where the cells(hematopoietic stem cells (HSCs))responsible for generating red blood cells, white blood cells, and platelets reside. But a striking study from researchers at UC San Francisco (UCSF) is rewriting that narrative. According to new findings published in Blood, the lungs also contain active blood-forming stem cells, capable of producing not only red blood cells but also platelets and key immune cells. The discovery could have direct implications for stem cell therapies and transplant medicine. The UCSF research team, backed by the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health (NIH), first made this groundbreaking discovery in 2017when they found that mouse lungs were generating up to half of the animal's platelets, a surprising contribution for an organ never thought to be involved in hematopoiesis. These cells, structurally and functionally similar to bone marrow HSCs, weren't merely circulating through the lungs, but seemed to be living in there. To test how capable these cells actually were, scientists isolated HSCs from both lung and bone marrow tissue, grew them in laboratory conditions, and observed what they produced. 'Both types of HSCs thrived in our gold-standard stem cell experiment, but the lung HSC colonies made more red blood cells and megakaryocytes, while the bone marrow colonies tended to make more immune cells,' explained Mark Looney, MD, professor of medicine and laboratory medicine at UCSF and senior author of the study. Rethinking the bone marrow transplant Bone marrow transplants have long been used to treat cancers like leukemia and other blood-related conditions. They involve harvesting stem cells from a donor, often via a blood draw, and using them to rebuild a patient's blood system. But the UCSF team found that nearly 1 in 5 stem cells isolated in bone marrow transplants actually carried markers specific to lung-derived HSCs, suggesting that current stem cell harvests may be drawing from more than just the bone marrow. 'For decades, bone marrow transplants have been a lynchpin in the treatment of cancers like leukemia,' Looney said. 'The lung HSCs could prove to be a second and significant reservoir of these precious stem cells.' The team also demonstrated that human lung HSCs could restore bone marrow function in mice, a powerful indication that these cells aren't just present, they are fully operational. Why would lungs make blood? That question remains unanswered, but there are theories. 'The lungs are critical to blood circulation, so it's tantalizing to see the lung HSCs as an emergency reservoir for red blood cell and platelet production,' said Looney. One possibility is that these cells activate during times of stress or injury, when the body's demand for oxygen-carrying red cells or clot-forming platelets spikes. The lungs, always at the center of the oxygen exchange process, could provide a rapid-response supply.

Top music professor AXED from Glasgow music school after 16 years over relationship with female student
He was the head of jazz for 16 years and was awarded with an OBE in 2019 DISMISSED Top music professor AXED from Glasgow music school after 16 years over relationship with female student Click to share on X/Twitter (Opens in new window) Click to share on Facebook (Opens in new window) A TOP jazz professor has been sacked from a Glasgow music school after 16 years amid allegations over a relationship with a female student. Professor Tommy Smith was given the boot from his post as head of jazz at the Royal Conservatoire of Scotland (RCS) in Glasgow after the claims flagged to bosses. Sign up for Scottish Sun newsletter Sign up 2 Saxophonist Tommy Smith was sacked from his post as Head of Jazz at the RCS Credit: Alamy 2 The Royal Conservatoire of Scotland said it had launched a probe into the claims The prestigious music institution, which boasts King Charles as its patron, launched a probe into the claims and confirmed Smith has since been dismissed. The 58-year-old saxophonist, originally of Wester Hailes in Edinburgh, had been at the helm of jazz studies at the RCS for 16 years. In 2019, Smith was awarded an OBE for services to Jazz from Her Majesty Queen Elizabeth II. He founded the Scottish National Jazz Orchestra and the Tommy Smith Youth Jazz Orchestra, had a global touring career, numerous solo albums and established a record label in his name. A source close to the Conservatoire revealed that the allegations related to his relationship with a female student who was over the age of 18. They told the Scottish Mail on Sunday: "Tommy is a very self-confident man which, coupled with his reputation, gives him a definite magnetism in jazz circles. "But it came as a shock when somebody with such standing ended up being suspended from what is a very prestigious post. "The tip-off to the Royal Conservatoire came from a third party and, given the nature of the allegations, they had little option other than to suspend Tommy. "We all hoped a brilliant musician and tutor could get back to work as soon as possible. "It's hard to overestimate what he has done for jazz in Scotland. He's a generational talent. Dick Halligan performs Spinning Wheel with Blood, Sweat & Tears in 1969 "But the Conservatoire clearly couldn't see a way back for him." A spokesperson for the Royal Conservatoire of Scotland said: "Following a disciplinary investigation and hearing, Tommy Smith has been dismissed. RCS has robust policies in place to ensure the safety and wellbeing of students and staff.' Tommy Smith was contacted for comment.
