Effect

• Heals for a Half Red Heart upon traveling to the next floor.
• Heals 50% of Isaac's empty Red Hearts and Bone Hearts (rounded down), but at minimum a half heart, upon traveling to the next floor.

Synergies

• Glowing Hour Glass: Returning to a previous floor will keep the health gained from Stem Cell, as well as granting another half-red heart after going down to the next floor again.
• Tainted Magdalene: Heals a lot of health back, usually resulting in full red health.

Interactions

• Blood Oath: The healing will occur before any health is drained.
• Tainted Bethany: Adds 1 to her "blood charges" resource.

Trivia

• A Stem Cell is an undifferentiated cell of a multicellular organism that is capable of giving rise to indefinitely more cells of the same type, and from which certain other kinds of cells arise by differentiation.
