In this paper, an approximate continuum poroelasticity model is developed to simulate the pressure evolution in the soft porous tissue during an SC injection. This poroelastic model mimics the deformation of the tissue by introducing the time variation of the interstitial fluid pressure. The advantage of this method lies in its computational time efficiency and simplicity, and it can accurately model the relaxation of pressure. The interstitial fluid pressure obtained using the proposed model is validated against both the analytical and the numerical solution of the poroelastic tissue model. The decreasing elasticity elongates the relaxation time of pressure, and the sensitivity of pressure relaxation to elasticity decreases with the hydraulic permeability, while the increasing porosity and permeability due to deformation alleviate the high pressure. An improved Kedem\u2013Katchalsky model is developed to study solute transport across the lymphatic vessel network, including convection and diffusion in the multi-layered poroelastic tissue with a hybrid discrete-continuum vessel network embedded inside. At last, the effect of different structures of the lymphatic vessel network, such as fractal trees and Voronoi structure, on the lymphatic uptake is investigated. In this paper, we provide a novel and time-efficient computational model for solute transport across the lymphatic vasculature connecting the microscopic properties of the lymphatic vessel membrane to the macroscopic drug absorption.<\/jats:p>","DOI":"10.3390\/biology12070942","type":"journal-article","created":{"date-parts":[[2023,7,3]],"date-time":"2023-07-03T01:03:02Z","timestamp":1688346182000},"page":"942","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Solute Transport across the Lymphatic Vasculature in a Soft Skin Tissue"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7937-0474","authenticated-orcid":false,"given":"Dingding","family":"Han","sequence":"first","affiliation":[{"name":"School of Mechanical Engineering, Purdue University, 585 Purdue Mall, West Lafayette, IN 47907, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ziyang","family":"Huang","sequence":"additional","affiliation":[{"name":"Mechanical Engineering Department, University of Michigan, Ann Arbor, MI 48109, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ehsan","family":"Rahimi","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Purdue University, 585 Purdue Mall, West Lafayette, IN 47907, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Arezoo M.","family":"Ardekani","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Purdue University, 585 Purdue Mall, West Lafayette, IN 47907, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,6,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"3","DOI":"10.1016\/S0169-409X(01)00150-8","article-title":"The physiology of the lymphatic system","volume":"50","author":"Swartz","year":"2001","journal-title":"Adv.
