Blastocoel Fluid Biopsy

Nematode Gastrulation: Having a BLASTocoel!

During gastrulation of the nematode worm Caenorhabditis elegans, individual cells ingress into a solid ball of cells. Gastrulation in a basal nematode, in contrast, has now been found to occur by invagination into a blastocoel, revealing an unanticipated embryological affinity between nematodes and all other triploblastic metazoans.

Nipple aspirate fluid—A liquid biopsy for diagnosing breast health

PURPOSE Nipple secretions are protein-rich and a potential source of breast cancer biomarkers for breast cancer screening. Previous studies of specific proteins have shown limited correlation with clinicopathological features. Our aim, in this pilot study, was to investigate the intra- and interpatient protein composition of nipple secretions and the implications for their use as liquid biopsie...

Fluid leak from an iliac crest in a biopsy site.

[Collection and preservation of the pleural fluid and pleural biopsy].

The samples of pleural fluid obtained by thoracentesis for the diagnosis of transudates and exudates shall follow a routine of collection and preservation for an appropriate laboratorial analysis. Equally, fragments of pleura biopsy obtained for the differential diagnosis of the exudates should be collected in a systematic way in order to optimize the diagnosis and facilitate the institution of...

The relationship between cleavage and blastocoel formation in Xenopus laevis

The development of the blastocoel in Xenopus laevis was studied by electron microscopy. Two major morphological specializations were associated both with blastocoel formation and with cleavage. The first specialization was the formation of close junctions at specific points along cleavage furrows, starting as early as the first division. The second was the secretion of material into the blastoc...
