A stroke is caused by oxygen deprivation or blood deficiency in the brain, causing neurons to die off within hours. If the motor cortex is damaged, it causes paralysis. Once the symptoms last for more than six months, there's little hope for recovery.

Stem cells have the unique ability to develop into specialized cell types in the body. By guiding that development, diseased or damaged tissue can be repaired. Bone marrow transplants have been used to treat leukemia because they contain hematopoietic stem cells, which regenerate blood cells. Dr. Lin has tried using hematopoietic stem cells to treat chronic stroke before, but the results were not ideal.
According to this paragraph, what does the narrator mean when he says, “the results were not ideal”?
Only experienced doctors can successfully use hematopoietic stem cells to treat chronic stroke.
Just like bone marrow transplants, doctors can also treat patients suffering from chronic stroke by using hematopoietic stem cells.
Although using hematopoietic stem cells is not the best way to treat chronic stroke, it can still help patients fully recover.
Chronic stroke cannot be entirely cured by using hematopoietic stem cells therapy.

Taiwan's doctors and biotech experts must work together to develop the stem cell therapy for patients suffering from chronic stroke complications. First, the biotech team must achieve a critical mass of stem cells from a small sample size. Then, the surgical team must find a way to safely inject the cells directly into the patient's brain.
