Frans Kuypers is a biomedical researcher working in hematology, cellular metabolism, and stem cell biology. His research includes investigating the human placenta as a source of pluripotent and hematopoietic stem cells capable of differentiating into various cell types. His published work focuses extensively on sickle cell disease therapeutics, erythrocyte properties and deformability, and lipid metabolism.

A typical cord blood collection yields about 100 milliliters of blood, while a human placenta weighs roughly 1 kilogram.

"cord blood will be maybe 100 milliliters, which is about 3 ounces of blood, right? Okay, now a placenta is 1 kilogram, it's about 2 pounds of human tissue." (said at 0:08:05)

The claim bundles two separate physiological assertions: umbilical cord blood collection volume and human placental weight. 1. Cord blood collection volume: The speaker's estimate of approximately 100 mL is supported by clinical evidence. Studies evaluating standard umbilical cord blood collection techniques for banking or transfusion report typical mean or median yields ranging from roughly 65 mL to 110 mL (or ~107–111 g). 2. Placental weight: The speaker's claim that a human placenta weighs roughly 1 kilogram (about 2 pounds) is contradicted by standard anatomical and obstetrical data. The average weight of a normal, singleton term human placenta is approximately 500 grams (about 0.5 kg or 1.1 pounds), roughly half the claimed weight. A placental weight reaching 1,000 grams is pathological (placentomegaly), typically associated with maternal diabetes, severe infection, or fetal hydrops. Because the second assertion significantly misstates normal human placental weight, the overall claim is graded as contradicted.
