▲ Abstract：

Lymphoedema is a chronic debilitating disease caused by impaired lymphatic drainage and is characterized by tissue swelling, fat expansion, inflammation and fibrosis1,2. However, the exact mechanisms that drive lymphoedema are poorly understood. Although lymphatic vessels are known to transport cholesterol from peripheral tissues back to the systemic circulation3, the importance of impaired lymphatic drainage for cholesterol clearance in humans and its relevance to lymphoedema remain unknown. Here we show that lymphatic drainage insufficiency in human lymphoedema leads to excessive cholesterol accumulation in the lymphoedematous dermal tissue and around lymphatic vessels. Cholesterol deposition resulted in dermal adipose tissue remodelling, characterized by adipocyte hypertrophy and dysfunction, progressing to death and dermal fibrosis. Surgical intervention improved lymphatic drainage and reduced cholesterol deposition. Using two mouse models that reproduce features of human lymphoedema, we demonstrated that tissue swelling and dermal adipose tissue remodelling were ameliorated by the cholesterol-depleting agent cyclodextrin. Mechanistically, we demonstrated that cyclodextrin restored lymphatic drainage by promoting the regeneration of lymphatic vessels. This study unravels the role of impaired cholesterol clearance in driving lymphoedema and identifies tissue cholesterol as a promising therapeutic target for this currently incurable disease.

▲ Abstract：

Early development across vertebrates and insects critically relies on robustly reorganizing the cytoplasm of fertilized eggs into individualized cells. This intricate process is orchestrated by large microtubule structures that traverse the embryo, partitioning the cytoplasm into physically distinct and stable compartments. Here, despite the robustness of embryonic development, we uncover an intrinsic instability in cytoplasmic partitioning driven by the microtubule cytoskeleton. By combining experiments in cytoplasmic extract and in vivo, we reveal that embryos circumvent this instability through two distinct mechanisms: either by matching the cell-cycle duration to the time needed for the instability to unfold or by limiting microtubule nucleation. These regulatory mechanisms give rise to two possible strategies to fill the cytoplasm, which we experimentally demonstrate in zebrafish and Drosophila embryos, respectively. In zebrafish embryos, unstable microtubule waves fill the geometry of the entire embryo from the first division. Conversely, in Drosophila embryos, stable microtubule asters resulting from reduced microtubule nucleation gradually fill the cytoplasm throughout multiple divisions. Our results indicate that the temporal control of microtubule dynamics could have driven the evolutionary emergence of species-specific mechanisms for effective cytoplasmic organization. Furthermore, our study unveils a fundamental synergy between physical instabilities and biological clocks, uncovering universal strategies for rapid, robust and efficient spatial ordering in biological systems.
