Фагоцитоз апоптотических телец выполняют также другие клетки, не только макрофаги.
Данный факт никто не оспаривает.
... в конце концов естественное старение человека (пожилой и старческий возраст) вызывает дефицит фагоцитоза...
Опять правильно, и Вы не будете отрицать, что среди пожилого населения процент больных онкологическими заболеваниями выше.
Вы многое доказываете, а кто многое доказывает тот ничего не доказывает.
Я не доказываю, а опираюсь на выполненные работы. Вот неполная библиография.

Стволовые клетки могут развиваться в другом направлении - переродившись превратиться в раковые. Введение стволовых клеток для лечения или профилактики применяют при ограниченном круге заболеваний / состояний.
Для лечения уже образовавшейся опухоли введенные стволовые клетки могут лишь ухудшить ситуацию, так как станут делиться симметрично. А вот для профилактики рака при возникновении предпосылок запуска канцерогенеза но до начала возникновения опухоли стволовые клетки могут оказаться полезными. Безусловно, нужно заниматься и заниматься поиском этой грани, когда стволовые клетки будут благом, а когда станут злом.
