Thirty-seven gestational sacs were obtained by ovariohysterectomy, and the gestational age of the embryos\/fetuses was determined based on developmental characteristics. The placentas were measured and processed by routine histological techniques. Additionally, fresh tissue from a term placenta was processed for ultrastructural analysis. An in-depth histological analysis was performed, and several morphometric variables (placental and lamellar width, placental and labyrinthine thickness, area and number of decidual cells) were recorded and related mainly to gestational age. A significant increase was observed in fetal length from 31 dpc, while placental thickness rose until 39 dpc; lamellae became abundant, parallel, longer, and narrower. Many CTB cells gradually fused into the STB; however, it progressively reduced. Medium-sized decidual cells, arranged in groups at the junctional zone, were progressively incorporated into the lamellae; there, they persisted until term, decreasing in number and becoming larger and frequently binucleated. The description of temporal modifications in lamellar, trophoblastic, and decidual features widens current knowledge on feline placental morphogenesis. In addition, these findings might be valuable for elucidating mechanisms behind placental development, which in turn affect its efficiency.<\/jats:p>","DOI":"10.3390\/vetsci12030207","type":"journal-article","created":{"date-parts":[[2025,3,3]],"date-time":"2025-03-03T03:22:44Z","timestamp":1740972164000},"page":"207","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Histological Changes in the Cat Placenta Throughout Gestation"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0288-4378","authenticated-orcid":false,"given":"Gimena","family":"Gomez Castro","sequence":"first","affiliation":[{"name":"Laboratorio de Histolog\u00eda y Embriolog\u00eda Descriptiva, Experimental y Comparada (LHYEDEC), Facultad de Ciencias Veterinarias, Universidad Nacional de La Plata (FCV, UNLP), La Plata 1900, Argentina"},{"name":"Consejo Nacional de Investigaciones Cient\u00edficas y T\u00e9cnicas (CONICET), CABA C1425FQB, La Plata 1900, Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9919-0307","authenticated-orcid":false,"given":"Roc\u00edo","family":"Hern\u00e1ndez","sequence":"additional","affiliation":[{"name":"Laboratorio de Histolog\u00eda y Embriolog\u00eda Descriptiva, Experimental y Comparada (LHYEDEC), Facultad de Ciencias Veterinarias, Universidad Nacional de La Plata (FCV, UNLP), La Plata 1900, Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrea","family":"Cristofolini","sequence":"additional","affiliation":[{"name":"Consejo Nacional de Investigaciones Cient\u00edficas y T\u00e9cnicas (CONICET), CABA C1425FQB, La Plata 1900, Argentina"},{"name":"\u00c1rea de Microscop\u00eda Electr\u00f3nica, Departamento de Patolog\u00eda Animal, Facultad de Agronom\u00eda y Veterinaria, Universidad Nacional de R\u00edo Cuarto, R\u00edo Cuarto 5800, Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Enrique","family":"Portiansky","sequence":"additional","affiliation":[{"name":"Consejo Nacional de Investigaciones Cient\u00edficas y T\u00e9cnicas (CONICET), CABA C1425FQB, La Plata 1900, Argentina"},{"name":"Laboratorio de An\u00e1lisis de Im\u00e1genes (LAI), FCV, UNLP, La Plata 1900, Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cecilia","family":"Merkis","sequence":"additional","affiliation":[{"name":"\u00c1rea de Microscop\u00eda Electr\u00f3nica, Departamento de Patolog\u00eda Animal, Facultad de Agronom\u00eda y Veterinaria, Universidad Nacional de R\u00edo Cuarto, R\u00edo Cuarto 5800, Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Erika","family":"Badura","sequence":"additional","affiliation":[{"name":"C\u00e1tedra de Enfermedades de Aves y Pil\u00edferos, FCV, UNLP, La Plata 1900, Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luciano","family":"Casas","sequence":"additional","affiliation":[{"name":"Servicio de Atenci\u00f3n Cl\u00ednica Primaria de Peque\u00f1os Animales, Hospital Escuela, FCV, UNLP, La Plata 1900, Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claudio","family":"Barbeito","sequence":"additional","affiliation":[{"name":"Laboratorio de Histolog\u00eda y Embriolog\u00eda Descriptiva, Experimental y Comparada (LHYEDEC), Facultad de Ciencias Veterinarias, Universidad Nacional de La Plata (FCV, UNLP), La Plata 1900, Argentina"},{"name":"Consejo Nacional de Investigaciones Cient\u00edficas y T\u00e9cnicas (CONICET), CABA C1425FQB, La Plata 1900, Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M\u00f3nica","family":"Diessler","sequence":"additional","affiliation":[{"name":"Laboratorio de Histolog\u00eda y Embriolog\u00eda Descriptiva, Experimental y Comparada (LHYEDEC), Facultad de Ciencias Veterinarias, Universidad Nacional de La Plata (FCV, UNLP), La Plata 1900, Argentina"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,3,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Wooding, P., and Burton, G.
