Applying the zone concept described previously, we quantitatively analyzed fetal rat lung
development. The zone concept allowed us to coherently define reference spaces in the …

The primary aim of this morphological investigation was to elaborate a concept allowing us
to coherently define reference spaces for morphometric analysis of fetal lung development …

We studied the pattern of airways branching in the fetal rat lung in vitro. Lung primordia of
gestational ages 13, 14, and 15 days were allowed to grow in culture to a gestational age …

Combined morphometric and autoradiographic methods were used to analyze the postnatal
growth of rat lung from 1–21 days after birth. Each cell population had distinct growth …

In the rat lung the alveoli are formed in the early postnatal period. Within 3 weeks the
alveolar surface area increases more than five‐fold and the saccular lung reaches its mature …

The postnatal growth of the lung was quantitatively investigated in rats aged 1, 4, 7, 10, 13,
21, 44 and 131 days by light and electron microscopic morphometry. Lung volume (VL) …

Postnatal growth of the lung has been the subject of investigation and controversy for many
years. Koelliker (1881) believed that the adult structure of the lung was already present in …

Ontogenic changes of the pulmonary epithelium of the rat, ranging from fetal day 15 to 1
hour after birth (21st day), were observed using light and electron microscopy as well as …

The structural development of the fetal guinea pig lung is described and quantified
morphometrically in this report. At 35 days gestation the lung is in the pseudoglandular …

Postnatal lung development is not well characterized in mice, especially the time point when
alveolarization is completed. Using the total length and the length density of the free septal …
