Summary
Researchers developed a microsurgical technique for rat liver transplantation. This method successfully engrafted fetal liver and 3D bioprinted liver organoids, paving the way for future liver regeneration research.
Area of Science:
- Regenerative Medicine
- Surgical Innovation
- Organoid Technology
Background:
- Organ fabrication research utilizes extracellular matrix, cell sheets, and organoids.
- Successful in vitro generation of human liver tissue and its reformation in rodent models has been demonstrated.
- Liver organoid transplantation is a rapidly advancing field.
Purpose of the Study:
- To describe the developmental stages of rat fetal organs and liver structure.
- To review recent advancements in liver organoid transplantation.
- To present a novel microsurgical method for liver transplantation in rats.
Main Methods:
- A microsurgical procedure was developed to create a transected liver plane in rats.
- Liver lobes were fixed, ligated, and resected to form the transected plane.
- The transected plane was covered with omentum, and fetal liver or 3D bioprinted liver organoids were transplanted.
Main Results:
- The microsurgical method created an intact liver parenchyma plane without bleeding.
- Transplanted fetal liver and 3D bioprinted liver organoids successfully engrafted onto the host liver.
- The technique facilitated the integration of the graft with the host's vascular system.
Conclusions:
- The described microsurgical technique provides a viable method for liver transplantation in experimental models.
- This approach may establish an essential environment for liver growth by utilizing portal and arterial blood flow.
- Further research can build upon this method for enhanced liver regeneration and transplantation strategies.

00:49The Tongue and Taste Buds
41.0K
The surface of the tongue is covered with various small bumps called papillae, which either distribute what has been ingested (filiform papillae) or contain the sensory taste (or gustatory) receptor cells (fungiform, circumvallate, and foliate papillae). Embedded within each taste-related papilla are the taste buds—clusters of 30 to 100 gustatory receptor cells.

Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...

The microscopic anatomy of the liver is a complex and intricate system that comprises numerous structural units known as liver lobules, each of which is comparable in size to a sesame seed. These hexagonal structures consist of plates of liver cells or hepatocytes, which are characterized by their versatility and abundance of cellular apparatus like rough and smooth ER, Golgi apparatus, peroxisomes, and mitochondria.

The liver, an essential organ in the human body, performs over 200 vital functions that can be broadly categorized into metabolic, hematological, endocrine regulation, and bile production.
Metabolic Regulation:
The liver is the central organ involved in regulating blood composition. It stabilizes blood glucose levels, maintaining them within the range of 70–110 mg/dL. When these levels drop, the liver breaks down glycogen reserves and releases glucose into the bloodstream. It can...

The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.

The liver, the largest gland within the human body, is a firm and reddish-brown organ. This wedge-shaped structure weighs approximately 1.5 kg and occupies a significant portion of the right hypochondriac and epigastric regions. It extends more to the right of the body's midline than to the left.
Located under the diaphragm, the liver is almost entirely ensconced within the rib cage, providing it with substantial protection. Except for the superior most bare area, the liver's surface is...
