Stem Cells and Regeneration · USMLE Step 1

Which of the following is a key challenge in using stem cells for regenerative therapies in clinical practice?

  1. Lack of ability to differentiate into specialized cells
  2. Achieving proper differentiation without tumor formation
  3. Stem cells are unable to proliferate in vitro
  4. Stem cells only exist during embryonic development
Show answer and explanation

Correct answer: Achieving proper differentiation without tumor formation

A critical challenge is to control stem cell differentiation precisely to yield desired cell types and avoid risks such as teratoma or other unintended growth, which can complicate therapeutic applications.
