| _The structures differ from real human embryos in many ways,

| embryonic tissues, as well as the supporting yolk sac and
| placenta needed for further development._

| _The human stem cells used to derive hematoids can be created
| from any cell in the body. This means the approach also holds
| great potential for personalised medicine in the future, by
| allowing the production of blood that is fully compatible with
| a patient's own body._

| Perfect blood doping.

| Kind of sad that that's the first thing that comes to mind...

| I know these are scientists and a 'Human embryo model' is a

| it's a disaster from a marketing perspective. People will see
| 'human embryo' and it doesn't matter that it's just a model of
| one. You are now growing fetus-slaves.
|
| Please call it something else.
|
| Edit: they are calling it 'hematoids' and make it clear that it
| is quite different from an embryo. I'm not sure why it's compared
| to them in the first place then.

| cognitive and sensorial capacity.
