Is each individual cell of a complex organism equivalent to the entire organism. Genetically speaking, yes. This has now been demonstrated. An entire mouse has been generated from a single non-reproductive blood cell. An egg cell was also used, but eggs are not themselves viable nor reproductive. This finding makes it clear that there is nothing particularly special about an embryonic stem cell from a philosophical point of view. Real scientists have known this for years despite what religious or political forces may imagine. In 'Monty Python's The Meaning of Life' there is the song 'Every Sperm is Sacred.' This parody of absurd religious thinking now should to be changed to 'Every Cell is Sacred.'
People should have the right to reproduce as they see fit assuming they have paid their dues/taxes to society and are not through recklessness creating a malformed or diseased offspring in an artificial way. Scientists should have the right to experiment with whatever cells they want to which are created artificially and have no possibility of causing human suffering.
