Nitric oxide modulates branching morphogenesis in fetal rat lung explants.
Cells of the developing lung express the constitutive nitric oxide synthases (NOSs) I and III. The developmental importance of these enzymes is largely unknown, although a role for nitric oxide (NO) in the regulation of pulmonary blood flow at birth is established. Known effects of NO on transcription factors, apoptosis, and cellular proliferation, plus the time and spatial limits of pulmonary ...
متن کاملAdipose tissue explants and MDCK cells reciprocally regulate their morphogenesis in coculture.
Adipokine-producing fatty tissues, composed of preadipocytes, adipocytes, and mesenchymal stem cells, surround the kidney. To study the interaction between renal tubular cells and adipose tissue, we cocultured adipose tissue fragments and MDCK cells. MDCK cells in the coculture showed a taller columnar shape with improved organization of their microvilli and basal lamina than that seen in MDCK ...
متن کاملIn vitro morphogenesis of Eucalyptus grandis: effects of antibiotics on explants
Effects of increasing cefotaxime, carbenicillin and timentin concentrations on the in vitro morphogenesis of Eucalyptus grandis explants were evaluated. It was observed that carbenicillin and timentin increased the frequency of explant regenerating calluses and decreased necrosis up to 600 mg L-1, and that cefotaxime behaved similarly up to 300 mg L-1. At this level there was an increasing freq...
متن کاملAutomated Image Analysis of Lung Branching Morphogenesis from Microscopic Images of Fetal Rat Explants
BACKGROUND Regulating mechanisms of branching morphogenesis of fetal lung rat explants have been an essential tool for molecular research. This work presents a new methodology to accurately quantify the epithelial, outer contour, and peripheral airway buds of lung explants during cellular development from microscopic images. METHODS The outer contour was defined using an adaptive and multisca...
متن کاملCharacterising the effects of in vitro mechanical stimulation on morphogenesis of developing limb explants
Mechanical forces due to fetal movements play an important role in joint shape morphogenesis, and abnormalities of the joints relating to abnormal fetal movements can have long-term health implications. While mechanical stimulation during development has been shown to be important for joint shape, the relationship between the quantity of mechanical stimulation and the growth and shape change of...
