During liver development, cytokines released from various cell types are critical for stem/progenitor cell differentiation and lineage expansions. (elsevierpure.com)
Recent advances in live imaging and genetics of mammalian division, movement and cell differentiation leading to development which integrate observations of biochemical tissue formation [14 ]. (lu.se)

For identifying lineage conversion and maturation, we utilized conventional assays of cell morphology, gene expression analysis and lineage markers. (elsevierpure.com)

Interestingly, cyclin D1 and CDC42 proteins are coexpressed temporally with the oval cell protein marker AFP. (uni-goettingen.de)

The effects of RAS blockade on liver regeneration and CRCLM in the regenerating liver were determined to investigate its potential benefits as a therapeutic avenue for CRCLM patients. (edu.au)

To our knowledge, few studies have investigated the relationship between the results of CT texture analysis and rate of liver regeneration after right hepatectomy in patients with HCCs. (hindawi.com)
Patients will be observed regularly for up to 1 year with regular blood test, ultrasound scans and a type of MRI scan that will tells us how well the liver is functioning. (ukri.org)

Furthermore, thrombocytes have been found to play a crucial role, not only during the initiation period, but throughout all phases of liver regeneration. (tellvienna.com)

Identification of central regulators and processes involved in the initiation of liver regeneration. (tellvienna.com)
We are focused on characterizing regeneration processes using a simple approach. (lu.se)
There are a lot of incredible sequencing technologies now that have let us characterize the regeneration processes at a level that we couldn't have imagined just 10 years ago. (lu.se)

The first manifestations of liver cancer are usually nonspecific, delaying the diagnosis. (msdmanuals.com)

Transjugular portography demonstrates extensive portal vein thrombus in the whole-liver allograft of a 40-year-old woman whose clinical condition rapidly deteriorated on postoperative day 39. (medscape.com)
The other major inflow vessel is the portal vein which carries 70-85% of the blood into the liver. (medscape.com)

The team found that bird species with a 'live fast die young' strategy develop quicker, allowing them to maximize the number of offspring they can produce in the short time they have available. (scitechdaily.com)
