Stem cells provide huge potential for finding treatments and cures to a vast array of medical issues: Different diseases—including cancers, Alzheimer's, Parkinson's, and more—can be treated with stem cells by replacing damaged or diseased tissue.This can include neurons that might affect neurological diseases and even entire organs that need to be replaced.Once harvested from an embryo, stem cells require several months of growth before they can be used.
First, they are unspecialized cells capable of renewing themselves through cell division, sometimes after long periods of inactivity.
Second, under certain physiologic or experimental conditions, they can be induced to become tissue- or organ-specific cells with special functions.
For those who believe God created people, the prospect of people creating people is troublesome.
In 1998, the first published research paper on the topic reported that stem cells could be taken from human embryos.
Until recently, scientists primarily worked with two kinds of stem cells from animals and humans: embryonic stem cells and non-embryonic "somatic" or "adult" stem cells.
The functions and characteristics of these cells will be explained in this document.A similar theological problem is an idea of creating living tissue in a laboratory and whether that represents humans taking on the role of God.This argument also applies to the potential for human cloning.One of the areas of potential is embryonic treatment.This stage of pregnancy is when many birth defects or other potential issues begin.In 2016, researchers in Scotland began working on the possibility of generating red blood cells from stem cells in order to create a large supply of blood for transfusions.A few years earlier, researchers in England began working on polymers derived from bacteria that can be used to repair damaged heart tissue.The use of embryonic stem cells for research involves the destruction of blastocysts formed from laboratory-fertilized human eggs.For those who believe that life begins at conception, the blastocyst is a human life, and to destroy it is unacceptable and immoral.Debates over the ethics of studying embryonic stem cells continued for nearly a decade until the use of adult-derived stem cells—known as induced pluripotent stem cells (IPSCs)—became more prevalent and alleviated those concerns.Use of adult-derived stem cells—known as induced pluripotent stem cells (IPSCs)—from blood, cord blood, skin, and other tissues have been demonstrated as effective in treating different diseases in animal models.
