…THE CRITICAL ROLE OF REPLENISHING OUR FOOD SUPPLY OF BLOOD CELLS (RED & WHITE BLOOD CELLS AND PLATELETS) THROUGHOUT THE PERSON'S LIFE SPAN. "CONCLUSION" ALTHOUGH STEM CELL TECHNOLOGY IS STILL IN ITS EARLY STAGES OF DEVELOPMENT, THERE HAS BEEN AN INCREASE IN STEM CELL RESEARCH AND FUNDING. THEREFORE, SCIENTISTS WILL BE PERMITTED TO DISCOVER MORE ABOUT CELL DEVELOPMENT AND FACTORS INVOLVED IN CELL DIFFERENTIATION AND WHICH SIGNALS ARE RESPONSIBLE FOR SWITCHING GENES ON & OFF.
