Historic Stage 14 Embryos
- H. Braus, 6-mm embryo, Heidelberg. Enlarged views of this well-preserved curettage specimen are included in the Hochstetter (1907)[1] Cited by Streeter (1945).[2] portfolio of pictures of the outer form of a series of human embryos. The nasal plate is more advanced than in others of this stage, but the limb buds are like those of the older members of the group.
- E. Gasser, 6.5-mm. Leyding embryo, Marburg Anatomisches Institut. Description of this advanced embryo is in the Keibel and Elze Normentafeln (1908).[3]
- J. A. Hammar, 5-mm Vestberg embryo, Anatomisches Institut, Uppsala. Embryo described by Hammar in the Keibel and Elze Normentafeln.[3] Typical sections and models of the pharyngeal region and gut are illustrated. This well-preserved embryo has been studied by several investigators, including Hammar on the development of the foregut, salivary glands, and tongue, and Broman on the development of the diaphragm and omental bursa.
- His, embryo R, 5.5 mm. Illustrated by His (1885).[4] It was concluded by His that this embryo approximated the Fol embryo (stage 13). The lens pit indicates stage 14. This assignment is supported by other features: e.g., the ductus venosus.
- His, embryo B, 7 mm, and embryo A, 7.5 mm. These two embryos are described jointly, in great detail, by His (1880).[4] Embryo A is evidently a little more advanced than embryo B and perhaps should be placed in stage 15.
- Keibel, 6.5-mm embryo “forensis.” Embryo described in the Keibel and Elze Normentafeln.[3] This embryo was used by Keibel in a series of studies on the development of the urogenital system.
- Keibel, 6.8-mm embryo, No. 501. Embryo included in the Keibel and Elze Normentafeln.[3] It is described in monographic form by Piper (1900).[5]
- Strabl, 6.75-mm embryo (Walther), Giessen. Described in the Keibel and Elze Normentafeln.[3]The external form is pictured by Hirschland (1898).[6]
- 6.5-mm embryo, University of Minnesota. Drawings of external views of this and of a 2.9-mm (stage 11) embryo were published by Wells and Kaiser (1959).[7]
- Free Hospital for Women, Brookline, Massachusetts, No. 33, 6 mm, No. 29, 7 mm, and No. 31, 7 mm. The histochemistry of these embryos of stage 14 was studied by McKay et al. (1956).[8]
