Objetivos

Describir la distribución celular y el grado de expresión de diversas hormonas y receptores de opioides en el desarrollo embrionario y en el pulmón sano del adulto

Método

Seleccionamos tejido pulmonar de las tres etapas del desarrollo fetal (seudoglandular, canalicular y sacular, tres muestras por etapa), de recién nacidos (tres), niños de 10 meses (dos) y adultos (tres) fallecidos sin afección pulmonar. Practicamos tinción inmunohistoquímica para hormonas específicas (calcitonina, parathormona, serotonina y hormona adrenocorticotropa [ACTH]) y receptores de opioides tipo delta y mu. Valoramos el porcentaje de células positivas así como el tipo celular reactivo en cada caso

Resultados

La serotonina es la primera en aparecer (estadio seudoglandular en células neuroendocrinas aisladas) para posteriormente desaparecer. La calcitonina aparece en el estadio canalicular en células neuroendocrinas y neumocitos. Su expresión máxima es al nacimiento y disminuye en el pulmón adulto. No hemos encontrado producción de ACTH ni de parathormona. Los receptores de opioides aparecen en la fase canalicular y alcanzan el máximo grado en el nacimiento. En el adulto sólo existen receptores para opioides tipo delta en neumocitos, células musculares bronquiolares y mesoteliales

Conclusiones

La hormonosecreción pulmonar es importante durante el desarrollo fetal y alcanza su máxima expresión en el nacimiento. La principal hormona que produce el pulmón fetal es la calcitonina. Existen receptores opioides durante el desarrollo fetal en diferentes tipos celulares y alcanzan su máxima expresión al nacimiento. El conocimiento de la expresión de sustancias activas podría tener consecuencias terapéuticas en determinados procesos patológicos como el síndrome de distrés respiratorio en el niño o el asma bronquial

Objectives

To describe the cellular distribution and level of expression of certain hormones and opioid receptors during fetal development and in the lung of the healthy adult

Method

We sampled lung tissue from fetuses at three stages of development (pseudoglandular, canalicular and saccular) (3 samples per stage), from newborn infants (3), from 10-month-old infants (2) and from adults (3) who had died without lung disease. After specific immunohistochemical staining for hormones (calcitonin, parathormone, serotonin and adrenocorticotropic hormone - ACTH) and opioid receptors, we assessed the percentage of positive cells for each cell type in each sample

Results

Serotonin is the first to appear (pseudoglandular stage in isolated neuroendocrine cells) and it disappears later. Calcitonin appears in the canalicular stage in neuro-endocrine and lung cells. Expression is at its peak at birth and is less in the adult lung. We found no ACTH or parathormone production. Opioid receptors appear in the canalicular stage and peak at birth. In adult lung, bronchiolar muscle and mesothelial cells, only deltatype opioid receptors are present

Conclusions

Pulmonary hormone secretion is significant during fetal development and peaks at birth. Calcitonin is the main hormone produced in the fetal lung. Opioid receptors are present during fetal development in various types of cells and peak at birth. An understanding of the expression of active substances could have therapeutic relevance in certain conditions, such as bronchial asthma or respiratory distress syndrome in the child
