The lung structural studies of Boyden are the subject of a separate report (1) and demonstrate that the maturational proc- ess is comparable to that of the human fetus (2), proceeding through a pseudoglandular and a canalicular stage to a final phase of alveolar formation and development. ...
Fetal Development of Fasciae around the Arm and Thigh Muscles: A Study Using Late Stage Fetusesmuscle fascialaminationmacrophagedesminhuman fetusTo obtain a better understanding of multi-laminar deep fascia covering skeletal muscles, we examined nondecalcified histological sections of the arm and thigh ...
The fetal stage (8 weeks to birth) is characterized by a rapid increase in complexity and differentiation of the organs. The fetus becomes active and most of its systems become operational. What are the threats to the fetal environment, and what can be done about them? • Factors in the...
In the present paper, we describe in detail for the first time the prominent thickening of the endothoracic fascia (ET)/developing parietal pleura in the fetal elephant at an early stage of gestation, and we compare it with the appearances of the pleura in fetuses of human, rabbit, rat ...
Transgenic expression of HEBAlt in HEB/ precursors, however, upregulated pT and allowed development to CD4+CD8+ stage in fetal thymocytes. Moreover, HEBAlt did overcome the CD3 signaling defect in HEB/Rag-1/ thymocytes. The HEBAlt transgene did not permit Rag-1/ precursors to bypass -...
The stage of gestation was assessed from palpation per rectum in early-to-mid gestation and at slaughter and from fetal development characteristics at slaughter. The age and breed of the cow and the sex of the fetus did not significantly affect any of the uterine components or fetal ...
The timing of treatment for stage I-B cervical carcinoma diagnosed during pregnancy is complicated by conflicting concerns for fetal survival and control of malignancy. There were 11 pregnant women with stage I-B cervical carcinoma diagnosed prior to fetal viability since 1969. Six patients were mana...
We studied effects of maternal age, body mass, and parturition date on birth mass and stage of development at birth in harbor seals (Phoca vitulina) on Sable Island, Nova Scotia, over a 10-year period. As predicted, effects of maternal mass and age on pup traits varied with maternal age...

During the saccular stage, which follows and lasts until birth, the growth of the pulmonary parenchyma, the thinning of the connective tissue between the airspaces, and the further maturation of the surfactant system are the most important steps towards life. At birth, although already functional...
