  • I asked chatGPT how stem cells are collected:

    From embryos: In the very early stages of development (usually from leftover embryos from fertility treatments), stem cells can be extracted. These are called embryonic stem cells and have the potential to turn into any cell type in the body.

    From adult tissues: Adults have stem cells in certain parts of their bodies, like the bone marrow, fat tissue, and blood. These are called adult stem cells and can usually turn into a few specific cell types (not as flexible as embryonic ones).

    From umbilical cord blood: After a baby is born, the blood from the umbilical cord and placenta is rich in stem cells. These cells are collected and can be stored for future medical use.

    Induced pluripotent stem cells (iPSCs): Scientists can take regular cells from the body, like skin cells, and reprogram them in a lab to behave like stem cells. These lab-created stem cells can act like embryonic stem cells and turn into many different types of cells.

    Anecdotally:

    There’s an epidemic of post-pandemic burn out and depression. It’s not just the pandemic, it’s the endless layoffs, the world is in a state of political unrest, the list goes on.

    It’s hard to decline and invite with that “excuse”, so many people accept.

    Attending a happy, social event where they will have to mask their emotions feels like an impossible mountain to climb.

    It’s a painful experience to be on the receiving end of this equation and I’m sorry it’s happening to you. I’m hoping this is just a reminder that it’s likely not personal, even though it very much feels that way.
