I think that your answer would be at least 200 to 300 cells that make up a blastocyst.

Hope this helps

Answer:

A blastocyst comprises of about 200 - 300 cells, following rapid cleavage.

Step-by-step explanation:

In humans , blastocysts formation begins about 5 days after fertilizations.

The blastocyst has a diameter of about 0.1 - 0.2 mm .

The inner cell mass is also a source of embryonic stem cells.
