Regenerative Potential of Hydrogels for Intracerebral Hemorrhage: Lessons from Ischemic Stroke and Traumatic Brain Injury Research. Adv Healthc Mater 2021; 10:e2100455.

Abstract
Intracerebral hemorrhage (ICH) is a deadly and debilitating type of stroke, caused by the rupture of cerebral blood vessels. To date, there are no restorative interventions approved for use in ICH patients, highlighting a critical unmet need. ICH shares some pathological features with other acute brain injuries such as ischemic stroke (IS) and traumatic brain injury (TBI), including the loss of brain tissue, disruption of the blood-brain barrier, and activation of a potent inflammatory response. New biomaterials such as hydrogels have been recently investigated for their therapeutic benefit in both experimental IS and TBI, owing to their provision of architectural support for damaged brain tissue and ability to deliver cellular and molecular therapies. Conversely, research on the use of hydrogels for ICH therapy is still in its infancy, with very few published reports investigating their therapeutic potential. Here, the published use of hydrogels in experimental ICH is commented upon and how approaches reported in the IS and TBI fields may be applied to ICH research to inform the design of future therapies is described. Unique aspects of ICH that are distinct from IS and TBI that should be considered when translating biomaterial-based therapies between disease models are also highlighted.

Biomaterials 2020; 236:119825. [PMID: 32044576 DOI: 10.1016/j.biomaterials.2020.119825] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2019] [Revised: 01/07/2020] [Accepted: 01/25/2020] [Indexed: 01/02/2023]
Abstract
In situ restoration of severely damaged lung remains difficult due to its limited regeneration capacity after injury. Artificial lung scaffolds are emerging as potential substitutes, but it is still a challenge to reconstruct lung regeneration microenvironment in scaffold after lung resection injury. Here, a 3D biomimetic porous collagen scaffold with similar structure characteristics as lung is fabricated, and a novel collagen binding hepatocyte growth factor (CBD-HGF) is tethered on the collagen scaffold for maintaining the biomimetic function of HGF to improve the lung regeneration microenvironment. The biomimetic scaffold was implanted into the operative region of a rat partial lung resection model. The results revealed that vascular endothelial cells and endogenous alveolar stem cells entered the scaffold at the early stage of regeneration. At the later stage, inflammation and fibrosis were attenuated, the microvascular and functional alveolar-like structures were formed, and the general morphology of the injured lung was restored. Taken together, the functional 3D biomimetic collagen scaffold facilitates recovery of the injured lung, alveolar regeneration, and angiogenesis after acute lung injury. Particularly, this is the first study of lung regeneration in vivo guided by biomimetic collagen scaffold materials, which supports the concept that tissue engineering is an effective strategy for alveolar regeneration.

[PMID: 30016724 DOI: 10.1016/j.brainresbull.2018.07.006] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2017] [Revised: 07/09/2018] [Accepted: 07/11/2018] [Indexed: 11/25/2022]
Abstract
OBJECTIVE Hydrogen inhalation has been found to be neuroprotective and anti-oxidative in several brain injury models. Building on these studies, we investigated potential neuroprotective effects of hydrogen inhalation in a rat model of intracerebral hemorrhage (ICH), focusing on apoptosis and inflammation. METHODS Forty-five 8-week-old male Sprague-Dawley rats were randomly divided into three groups (n = 15 per each group): a sham group, ICH group, and ICH + hydrogen group. Induction of ICH was performed via injection of 0.23 U of bacterial collagenase type IV into the left striatum. Hydrogen was administered via spontaneous inhalation. Mortality and neurologic deficits were investigated at 6, 24, and 48 h after ICH. To investigate the antioxidative activity of hydrogen gas, the expression of malondialdehyde was measured. Real-time polymerase chain reaction analyses of TNF-a, IL-1b, BDNF, and caspase-3 expression were used to detect anti-inflammatory and anti-apoptotic effects. Neuroprotective effect was evaluated by immunohistochemical and TUNEL staining. RESULT At 6, 24 and 48 h post-intracerebral hemorrhage, animals showed brain edema and neurologic deficits, accompanied by up-regulation of TNF-a, IL-b, BDNF, and caspase-3, which is indicative of neuroinflammation, neuroprotection, and apoptosis. Hydrogen treatment significantly reduced the level of oxidative stress, neuroinflammation, neuronal damage, and apoptosis-related genes. This was accompanied by increased neurogenesis and expression of growth factor-related genes at <24 h, but not 48 h, after ICH. CONCLUSION H2 gas administration exerted a neuroprotective effect against early brain injury after ICH through anti-inflammatory, neuroprotective, anti-apoptotic, and antioxidative activity.

Abstract
Hemorrhagic stroke accounts for 10-15% of all strokes and is strongly
associated with mortality and morbidity worldwide, but its prevention and
therapeutic interventions remain a major challenge. Here, we report the
identification of miconazole as a hemorrhagic suppressor by a small-molecule
screen in zebrafish. We found that a hypomorphic mutant fn40a,
one of several known β-pix mutant alleles in zebrafish,
had the major symptoms of brain hemorrhage, vessel rupture and inflammation as
those in hemorrhagic stroke patients. A small-molecule screen with mutant
embryos identified the anti-fungal drug miconazole as a potent hemorrhagic
suppressor. Miconazole inhibited both brain hemorrhages in zebrafish and
mesenteric hemorrhages in rats by decreasing matrix metalloproteinase 9
(MMP9)-dependent vessel rupture. Mechanistically, miconazole downregulated the
levels of pErk and Mmp9 to protect vascular integrity in fn40a
mutants. Therefore, our findings demonstrate that miconazole protects blood
vessels from hemorrhages by downregulating the pERK-MMP9 axis from zebrafish to
mammals and shed light on the potential of phenotype-based screens in zebrafish
for the discovery of new drug candidates and chemical probes for hemorrhagic
stroke. Summary: A phenotype-based chemical screen in zebrafish identifies
miconazole as a novel hemorrhagic suppressor. Miconazole inhibits vessel rupture
and hemorrhages by decreasing pErk and MMP9 in zebrafish and rats.
