**Core Concept**
Hematopoietic stem cells (HSCs) are multipotent cells capable of self-renewal and differentiation into all blood cell types. They are distinct from progenitor stem cells, which have a more limited range of differentiation potential.

**Why the Correct Answer is Right**
HSCs possess the unique ability to give rise to all hematopoietic cell lineages, including myeloid, lymphoid, erythroid, megakaryocytic, and mast cell lineages. This is due to their capacity for **self-renewal**, allowing them to maintain their population, and **pluripotency**, enabling them to differentiate into any blood cell type. The presence of specific transcription factors, such as Hoxa9, Meis1, and Runx1, also contributes to the hematopoietic fate of HSCs.

**Why Each Wrong Option is Incorrect**
**Option A:** HSCs cannot differentiate into all cell types, only those within the hematopoietic lineage.
**Option B:** Progenitor stem cells also possess the ability to differentiate into multiple cell types, but their range is limited compared to HSCs.
**Option C:** While HSCs can differentiate into various cell types, this option is too vague and does not accurately capture their unique characteristics.

**Clinical Pearl / High-Yield Fact**
It is essential to note that HSCs are not only responsible for hematopoiesis but also contribute to the development of hematological malignancies, such as leukemia, when their regulation is disrupted.

**Correct Answer: D. Differentiate into all hematopoietic cell lineages.**
