Biol Reprod . 2022 Jan; 106(4):814-822. PMID: 35040958
Mature granulated trophoblast binucleate cells (BNC) have been found in all ruminant placentas examined histologically so far. BNC are normally fairly evenly distributed throughout the fetal villus and all their...

Placenta . 2020 May; 95:91-105. PMID: 32452408
Introduction: The impala is a widely distributed African ungulate. Detailed studies of the placenta and ovaries in impala undertaken in the 1970s did not address the endocrine functions of the...

Wilsher S, Rigali F, Couto G, Camargo S, Allen W
Equine Vet J . 2018 Nov; 51(4):500-505. PMID: 30417442
Background: Historically, cryopreservation of equine embryos >300 μm gave poor pregnancy rates until researchers collapsed the blastocoele cavity and aspirated the blastocoele fluid prior to vitrification. Objective: To determine if...

Bracher V, Mathias S, Allen W
Equine Vet J . 2017 Oct; 28(3):180-188. PMID: 28976715
Placentation between 80 and 220 days of gestation was studied by measurement of fetal dimensions and gross, light and transmission and scanning electron microscopic examinations of the allantochorion and endometrium...

Equine Vet J . 2017 Oct; 50(1):10-21. PMID: 28971522
Over the past 50 years, per season pregnancy rate in Thoroughbred mares have risen from 70 to >90% and foaling rates from 55 to >80%. Some of the significant pharmacological...

Placenta . 2016 Nov; 48:1-12. PMID: 27871459
Introduction: There are few descriptions of the placenta and associated tissues of the European hedgehog (Erinaceus europaeus) and here we present findings on a near-term pregnant specimen. Methods: Tissues were...

Mol Phylogenet Evol . 2014 Dec; 83:184-90. PMID: 25527317
The placenta of ruminants contains characteristic binucleate cells (BNC) with a highly conserved glycan structure which evolved early in Ruminant phylogenesis. Giraffe and Okapi placentae also contain these cells and...

Placenta . 2014 Dec; 36(1):77-87. PMID: 25465705
Introduction: The trophoblast binucleate cell [BNC] is central to the structure and function of all ruminant placentas so far investigated. The Giraffidae are considered to form a separate family within...

Antczak D, de Mestre A, Wilsher S, Allen W
Annu Rev Anim Biosci . 2014 Nov; 1:419-42. PMID: 25387026
A remarkable feature of equine pregnancy is the development of the invasive trophoblast of the chorionic girdle and its formation of the gonadotrophin-secreting endometrial cup cells in early gestation. The...
