网页The intersection of stem cell technology, genetic engineering, and cloning poses both scientific and ethical challenges. Before we consider how molecular cloning works, watch this video to learn what stem cells are and how they form:
Stem cells: What they are and what they do - Mayo Clinic
网页2024年3月23日 · Stem cells are a special type of cells that have two important properties. They are able to make more cells like themselves. That is, they self-renew. And they can become other cells that do different things in a process known as differentiation. Stem cells are found in almost all tissues of the body.
How Stem Cell Cloning Works (Infographic) - Live Science
网页2013年5月16日 · Cloning can be used to produce a supply of unspecialized stem cells that can be induced to grow into various types of body cells.
Human stem cells created by cloning - Nature
网页2013年5月15日 · Most groups gave up long ago on the finicky core method — production of patient-specific embryonic stem cells (ESCs) from cloning.
What is cloning, and what does it have to do with stem cell …
网页Cloning, or somatic cell nuclear transfer (SCNT), is the technique used to produce Dolly the sheep, the first animal to be produced as a genetic copy of another adult. In this procedure, the nucleus of an egg cell is removed and replaced by the nucleus of a …
Cloning produces human embryonic stem cells - Science News
网页2013年5月15日 · For the first time, scientists have created human embryonic stem cells by transferring the nucleus of a mature cell into an egg. The cloning technique could nudge the dream of personalized...
Embryos, Cloning, Stem Cells, and the Promise of Reprogramming
网页In the absence of any evidence that reproductive cloning of mammals, yielding full-fledged progeny, was possible, the panel thought about nuclear transfer simply as a means to generate cloned embryos and useful stem cell lines for study and therapy—a strategy now called therapeutic cloning.
Efficient and safe single-cell cloning of human pluripotent stem cells ...
网页2022年10月19日 · Single-cell cloning is a mainstay of stem cell biology and represents the most rigorous assay to investigate self-renewal and differentiation, which are the key defining properties of stem...
An Efficient Protocol for Single-Cell Cloning Human Pluripotent Stem Cells
网页2019年1月31日 · However, when >50 single-cell clones are needed, such as when genetically modifying the cells, manual colony picking is not ideal as the process is both labor-intensive and inefficient. Here, I provide a detailed procedure for the high efficiency single-cell cloning of hPSCs.
Stem cells made by cloning adult humans | Nature
网页2014年4月28日 · Two research groups have independently produced human embryonic stem-cell lines from embryos cloned from adult cells. Their success could reinvigorate efforts to use such cells to make...
