Physicians involved in regenerative medicine research conduct a series of animal experiments to determine pulmonary tissue regeneration capacity. During one of the experiments, lung alveoli are exposed to NO₂ and massive necrosis of the epithelial lining ensues.

This regenerated tissue is most likely derived from which of the following cell types?
