Cellular Adaptation IV: Dysplasia and Metaplasia
0 Views •
2026
DysplasiaDysplasia refers to abnormal changes in the size, shape, and organization of mature cells, characterized by pleomorphism, nuclear abnormalities, and increased mitotic activity. It commonly affects epithelial tissues, including the cervix, gastrointestinal tract, respiratory mucosa, and endometrium. Although it may occur alongside hyperplasia, dysplasia is not a true adaptive response but a preneoplastic change with potential to progress to cancer.When confined above the basement...

2024
This work describes a novel surgical technique for extracapsular implantation of a personalized, 3-dimensional-printed, joint-preserving implant. This novel treatment aims to restore hip stability in young adult dogs suffering from hip dysplasia with laxity by uniquely reproducing the anatomical shape of the acetabular rim of the hip joint.

This protocol describes the development of a neonatal piglet model of acute lung injury that models early pathogenic events occurring in the preterm lung, including sub-adequate surfactant quantity, hyperoxia, high-pressure ventilation, and inflammation, to facilitate understanding of molecular triggers of bronchopulmonary dysplasia and enhance therapeutic translation.

Gene Silencing with Morpholinos
0 Views •
2023
Morpholino-mediated gene silencing is a common technique used to study roles of specific genes during development. Morpholinos inhibit gene expression by hybridizing to complementary mRNAs. Due to their unique chemistry, morpholinos are easy to produce and store, which makes them remarkably cost effective compared to other gene silencing methods. This video reviews proper experimental design when using these oligonucleotides. Following that, an explanation of morpholino microinjection...
FAQs
Clinical grading uses the mild, moderate, and severe categories to communicate how extensive the atypical changes appear within the examined tissue. The grade is not interpreted in isolation: clinicians consider the affected site and the patient’s risk factors before deciding what the finding means. This contextual reading helps distinguish surveillance needs from situations requiring treatment planning or early intervention.
At the cellular level, dysplasia can alter three linked features: maturation, polarity, and tissue architecture. Maturation refers to the normal progression of cell development, polarity describes organized cellular orientation, and architecture concerns the arrangement of cells within the tissue. Disruption of these features produces atypical organization and can impair function, while in some epithelial settings it may precede cancer.
Developmental dysplasias concern abnormal organization arising during development and may require diagnostic and functional assessment over time. Epithelial dysplasia is evaluated for atypical maturation and architecture, including its possible relationship to cancer risk. The distinction matters because one emphasizes developmental function, whereas the other often guides grading, surveillance, and intervention.
Clinical assessment may combine direct examination with imaging and histopathologic analysis. Examination and imaging help identify structural abnormalities, whereas histopathology evaluates cells and tissue organization in greater detail. Using these approaches together allows clinicians to classify the finding more accurately and to relate observed changes to the affected tissue.
Severity is interpreted alongside the tissue involved and the patient’s risk factors, rather than treated as a standalone result. This approach recognizes that clinical significance depends on context. The combined assessment supports a more appropriate decision about surveillance, treatment planning, or early intervention.
In epithelial disease, classification can support surveillance, treatment planning, and early intervention by indicating the seriousness of atypical tissue changes. In developmental dysplasias, assessment can instead help guide diagnosis, evaluate function, and shape long-term management. Thus, the clinical value extends beyond naming the abnormality.
