Walter Vogt (embryologist)
Walter Vogt was a German embryologist. He lived from 1888 to 1941. He was the first scientist to use vital dye to do fate mapping Fate mapping is a method used in developmental biology to study the embryonic origin of various adult tissues and structures. The "fate" of each cell or group of cells is mapped onto the embryo, showing which parts of the embryo will develop i .... In 1929, he used vital dyes to construct fate maps of amphibian embryos.

Embryologist
Embryology (from Greek ἔμβρυον, ''embryon'', "the unborn, embryo"; and -λογία, ''-logia'') is the branch of animal biology that studies the prenatal development of gametes (sex cells), fertilization, and development of embryos and fetuses. Additionally, embryology encompasses the study of congenital disorders that occur before birth, known as teratology. Early embryology was proposed by Marcello Malpighi, and known as preformationism, the theory that organisms develop from pre-existing miniature versions of themselves. Aristotle proposed the theory that is now accepted, epigenesis. Epigenesis is the idea that organisms develop from seed or egg in a sequence of steps. Modern embryology developed from the work of Karl Ernst von Baer, though accurate observations had been made in Italy by anatomists such as Aldrovandi and Leonardo da Vinci in the Renaissance. Comparative embryology Preformationism and epigenesis As recently as the 18th century, the prevailing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fate Mapping
Fate mapping is a method used in developmental biology to study the embryonic origin of various adult tissues and structures. The "fate" of each cell or group of cells is mapped onto the embryo, showing which parts of the embryo will develop into which tissue. When carried out at single-cell resolution, this process is called cell lineage tracing. It is also used to trace the development of tumors. Fate mapping and cell lineage are similar methods for tracing the history of cells. History Fate maps were created with the intent of tracing a specified region during the early developmental transition of an embryo to a distinct body structure. The first fate maps originate in the 1880s. The early fate maps in 1905 were created by Edwin Conklin and were based on direct observation of the embryos of ascidians (sea squirts) and other marine invertebrates. Modern fate mapping began in 1929 when Walter Vogt invented a process which involved marking a specific region of a developing e ...
