Final answer:

Acute lymphoblastic leukemia is subclassified into B-ALL and T-ALL based on specific surface markers. B-ALL is characterized by the expression of CD19 and CD10, while T-ALL is characterized by the expression of CD3 and CD5.

Step-by-step explanation:

Acute lymphoblastic leukemia (ALL) is subclassified into B-cell ALL (B-ALL) and T-cell ALL (T-ALL) based on surface markers, specifically cluster of differentiation (CD) molecules.

B-ALL is characterized by the expression of CD19 and CD10 on the surface of the cancerous cells, while T-ALL is characterized by the expression of CD3 and CD5.
