Building the complex architecture of tubular organs is a highly dynamic process that involves cell migration, polarization, shape changes, adhesion to neighboring cells and the extracellular matrix, physicochemical characteristics of the extracellular matrix and reciprocal signaling with the mesenchyme. Understanding these processes in vivo has been challenging as they take place over extended time periods deep within the developing organism. Here, I will discuss 3D in vitro models that have been crucial to understand many of the molecular and cellular mechanisms and key concepts underlying branching morphogenesis in vivo.

Extracellular matrix stiffness regulates colorectal cancer progression via HSF4.
J Exp Clin Cancer Res
January 2025
Department of General Surgery, Xiangya Hospital, Central South University, Changsha, Hunan, 410008, China.
Background: Colorectal cancer (CRC) has high incidence and mortality rates, with severe prognoses during invasion and metastasis stages. Despite advancements in diagnostic and therapeutic technologies, the impact of the tumour microenvironment, particularly extracellular matrix (ECM) stiffness, on CRC progression and metastasis is not fully understood.
Methods: This study included 107 CRC patients.
Depot-specific acetylation profiles of adipose tissues-therapeutic targets for metabolically unhealthy obesity.

The Centre for Cleft Lip and Palate Treatment, Plastic Surgery Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, 33 Badachu Road, Shijingshan District, Beijing, 100144, People's Republic of China.
Background: Adipose tissue plays a critical role in the development of metabolically unhealthy obesity (MUO), with distinct adipose depots demonstrating functional differences. This study aimed to investigate the unique characteristics of subcutaneous (SA) and visceral adipose tissue (VA) in MUO.
Methods: Paired omental VA and abdominal SA samples were obtained from four male patients with MUO and subjected to Four-Dimensional Data Independent Acquisition (4D-DIA) proteomic and lysine acetylation (Kac) analyses.
Drainage from intentional extramacular holes after internal limiting membrane insertion to treat macular hole retinal detachment in highly myopic eyes.

January 2025
Department of Ophthalmology, Central Theater General Hospital, 627 Wuluo Road, Wuhan, 430070, China.
Purpose: The purpose is to evaluate the effect of drainage from intentional extramacular holes after internal limiting membrane insertion to treat macular hole retinal detachment (MHRD) in highly myopic eyes.
Methods: This study is a retrospective, observational, and comparative case series that included 25 consecutive highly myopic eyes with MHRD. All eyes underwent standard 23-gauge vitrectomy, inverted internal limiting membrane insertion into the macular hole, subretinal fluid drainage from an intentionally created extramacular retinal hole, and tamponade with either silicone oil (SO group, n = 13) or perfluoropropane (CF group, n = 12).

Background: Mitral valve prolapse (MVP) is a common cardiac valvular anomaly that can be caused by mutations in genes of various biological pathways. Individuals of three generations of a kindred presented with apparently dominant heredity of isolated MVP.
Methods: Clinical evaluation and echocardiography for all complying family members (n=13).
Emerging roles of hyaluronic acid hydrogels in cancer treatment and wound healing: A review.
Int J Biol Macromol
January 2025
Center of Stem Cell and Regenerative Medicine, Gaozhou People's Hospital, No. 89 Xiguan Road, Gaozhou 525299, Guangdong, China. Electronic address:
Hyaluronic acid (HA)-derived hydrogels signify a noticeable development in biomedical uses, especially in cancer treatment and wound repair. Cancer continues to be one of the foremost causes of death globally, with current therapies frequently impeded by lack of specificity, serious side effects, and the emergence of resistance. HA hydrogels, characterized by their distinctive three-dimensional structure, hydrophilic nature, and biocompatibility, create an advanced platform for precise drug delivery, improving therapeutic results while minimizing systemic toxicity.
