Cambridge Researchers use Mouse Embryonic Stem Cells to Grow Artificial Mouse “Embryos”

Let’s start at the very beginning. When a mammalian egg is successfully fertilized by a single sperm, the result is a single cell called a zygote. A zygote has the potential to grow into a full-bodied organism. It is mind-boggling that this single cell, containing…

Synthetic Chimeras: Separating Science from Science Fiction

Earlier this year, scientists from the Belmonte lab at the Salk Institute (La Jolla, CA) reported the first successful grafting of human stem cells into pig embryos. In other words, they were able to merge human stem cells with a nonhuman embryo to create an organism called…

Are Stem Cells Just Tiny Normal Cells?

You’re at a social gathering and someone asks, “So, what do you do?” It’s meant to be a casual conversation starter, but do you ever find yourself taking a mental breath before answering? As an immunologist studying stem cells, I take that mental breath to…
