Stem cell research is the correct choice, as it focuses on the use of unspecialized human cells known as stem cells. These cells have the unique ability to divide and renew themselves for long periods and can differentiate into various specialized cell types. This capacity makes stem cells a vital component in regenerative medicine, offering the potential to repair or replace damaged tissues and organs.

In contrast, gene therapy involves the modification of genes within an individual's cells to treat or prevent disease, which does not specifically utilize unspecialized cells. Protein therapy leverages proteins to treat disease, while enzyme replacement therapy aims to provide enzymes that are deficient or absent in patients, particularly in certain genetic disorders. Therefore, these options do not center around the properties and applications of stem cells in the same way that stem cell research does.
